Antimony sulfide (Sb2S3) has emerged as a highly promising inorganic thin-film light-absorbing material owing to its suitable bandgap, high absorption coefficient, and excellent thermal stability. However, the deep-level defects and intrinsic carrier self-trapping effects arising from its quasi-one-dimensional crystal structure severely limit device efficiency. In this work, selenium (Se) was introduced via magnetron sputtering, followed by a thermally activated molecular-chain reconfiguration process to enhance lattice stability and carrier transport. During this process, Se atoms diffuse into the Sb2S3 lattice and migrate toward grain boundaries, forming a vertical compositional gradient that modulates film crystallinity, growth orientation, and band structure. Due to its larger atomic radius, Se incorporation induces slight lattice expansion and strain redistribution, effectively passivating sulfur vacancies and suppressing SSb antisite defects. Phonon-spectrum simulations and differential charge-density analyses confirm that Se incorporation mitigates lattice distortion, suppresses carrier self-trapping, and enhances carrier delocalization. The optimized Se-Sb2S3 films exhibit improved crystallinity, prolonged carrier lifetime, and reduced nonradiative recombination losses, achieving a power conversion efficiency of 7.82%. This study reveals a thermodynamically driven defect-passivation mechanism and provides a viable strategy for developing efficient and stable Sb2S3-based solar cells.
Lithium-sulfur (Li-S) batteries are regarded as a representative next-generation energy storage technology due to their high energy density, low cost, and environmental friendliness. Nevertheless, their widespread application is hindered by challenges such as the insulating nature of sulfur and Li2S, the larger volume expansion during cycling, and the serious side effects caused by the soluble lithium polysulfide (LiPSs), all of which collectively lead to severe capacity decay and poor cycling stability. Furthermore, the high flammability of sulfur is another critical safety concern, which has hindered its further application. To effectively address these limitations, this study designed and developed a flame-retardant sulfur cathode (CS@Al/APP) by encapsulating carbon-sulfur composites with aluminum hydroxide (Al(OH)3) and employing ammonium polyphosphate (APP) as a binder to enhance electrode stability and flame retardancy. Experimental results demonstrate that Al(OH)3 and APP synergistically improve the flame resistance by releasing inert gases and forming a protective char layer. Additionally, they enhance sulfur redox kinetics by efficiently trapping LiPSs. As a result, the CS@Al/APP cathode exhibits exceptional electrochemical stability, maintaining a reversible capacity of 1025.04 mAh g-1 after 100 cycles at 0.1C and delivering a discharge capacity of 744.2 mAh g-1 after 500 cycles at 1C. This study provides a feasible technical pathway for achieving lithium-sulfur batteries with high safety and high energy density.
Wide-bandgap perovskite solar cells (WBG-PSCs) are indispensable top-cell candidates for perovskite/silicon tandems that can overcome the theoretical limit of single-junction silicon solar cells. Their efficiencies, however, are hindered by the intrinsically rapid and non-uniform crystallization of mixed-cation, mixed-halide absorbers when upscaling on large-area substrates. This results in an increase in interfacial defects and bulk traps that compromise both efficiency and stability. Herein, we introduce 4-(trifluoromethyl)aniline hydrochloride (4-TFPA) into perovskite precursors to regulate rapid nucleation and slow crystallization of perovskite absorbers when transforming from a precursor solution to a solid film. This is enabled by the dual interaction of 4-TFPA with both lead (Pb2+) and formamidinium (FA(+)) ions-weak coordination with Pb2+ and strong hydrogen bonding with FA(+). The modified nucleation and crystallization processes are responsible for the reduction of defects in mixed-cation, mixed-halide perovskite absorbers. Moreover, the residual 4-TFPA in the final absorber further passivates defects and optimizes band alignment at the perovskite/electron-transport interface. The resulting perovskite mini-modules deliver a power-conversion efficiency of 21.90% (approximate to 1.68 eV) and 22.50% (approximate to 1.53 eV) on an aperture area of 22.96 cm(2) under sunlight illumination. Encapsulated mini-modules retain over 80% of their initial efficiencies for >700 h under both ISOS-D-1 and ISOS-L-1 protocols.
Tailoring the pore architecture of hard carbon anodes to minimize its contact area with electrolyte while maximizing ion transport channels remains a key challenge for achieving concurrent high initial Coulombic efficiency (ICE) and rapid reaction kinetics in sodium-ion batteries (SIBs). Herein, a facile and scalable interfacial molecular bridging strategy has been proposed to break this trade-off, enabling precise pore structure engineering by constructing 3D nitrogen-doped network structured intermediate through chemical cross-linking between lignin and folic acid via C(O)-O groups. Critically, this network promotes the transformation of open pores into closed pores, thereby yielding HC with ultralow specific surface area of 0.5 m2 g- 1 and higher closed pore volume of 0.23 cm3 g- 1. Concurrently, introducing pitch derived graphitic domains further creates efficient fast-track graphitic channels for Na+/electron transport. The resulting hard-soft HC anode achieves a record-high ICE of 95% (84% @ -20 degrees C) and remarkable rate performance of 230 mA h g- 1 at 6C, while maintaining 90% capacity retention after 1000 cycles at 1C. Furthermore, through in situ/ex situ tests and kinetic analysis, the adsorption-intercalation-pore filling storage mechanism has been fully elaborated. When constructed with Na3V2(PO4)3 cathode, the full cell delivers superior energy density of 272 W h kg- 1. This study represents a pivotal advance in the rational design of microstructure-precise HC anodes, paving the way for highperformance and commercially viable SIBs.
This study presents a comparative analysis of three major failure modes in n-type photovoltaic modules-hotspot effects, ultraviolet-induced degradation (UVID), and potential-induced degradation (PID)-to address critical reliability concerns. Using standardized IEC testing protocols, we systematically evaluated multiple module technologies. Key findings reveal the following: (1) the correlation between technological configurations and hotspot temperature distribution under extreme shading conditions; (2) the relative susceptibility of tunnel oxide passivating contact (TOPCon), heterojunction with intrinsic thin-layer (HJT), and back-contact (BC) prototypes to UVID; and (3) distinct PID mechanisms and degradation pathways at the front versus rear surfaces across different architectures. The results provide essential theoretical and empirical insights to support the development of more reliable photovoltaic products.
The rapid expansion of photovoltaic (PV) deployment has led to a substantial increase in waste crystalline silicon (c-Si) PV modules, creating urgent demands for efficient resource recovery and environmentally sustainable recycling. However, the separation behaviour of solder ribbons has been largely overlooked, and most existing physical separation methods are limited by a narrow particle size applicability. In this study, a high-efficiency recycling strategy based on dense medium separation was proposed for post-pyrolysis sorting of waste PV modules by exploiting the density differences among key components, including silicon wafers, glass, and solder ribbons. A stable ferrosilicon-based dense medium with adjustable densities ranging from 2.30 to 2.70 g/cm3 was developed to investigate the density-dependent separation behaviour of different materials. The results demonstrated that silicon wafers were preferentially separated at 2.30 g/cm3, while solder ribbons were completely settled at 2.70 g/cm3. Hydrocyclone experiments achieved complete recovery of solder ribbons under all tested conditions, and a combined recovery efficiency of silicon wafers and glass of 97.66% at a medium density of 2.40 g/cm3. To further optimize separation performance, computational fluid dynamics (CFD) simulations were conducted to elucidate the effects of cyclone structural parameters and inlet velocity on flow characteristics and particle migration behaviour, leading to the identification of an optimal cyclone configuration and a staged inlet velocity strategy. Based on the experimental and simulation results, a density-regulated two-stage separation route was established, in which silicon wafers were effectively separated from glass and solder ribbons at 2.30 g/cm3 with a wafer grade of 81.77%, followed by complete glass-solder ribbon separation at 2.70 g/cm3, yielding a glass grade of 100%. Furthermore, life cycle assessment (LCA) revealed that hydrocyclone separation exhibited lower carbon emissions (0.383 kg CO2 eq per kg treated material) and reduced overall environmental impacts compared with gas-solid fluidized bed separation. This study provides an environmentally favourable approach for the resource recovery of waste PV modules.
Operational stability of perovskite solar cells (PSCs) under temperature fluctuations poses a critical challenge for their practical application in extreme environments such as polar and aerospace regions. Although they exhibit commendable low-temperature performance, the operational degradation mechanism under cryogenic thermal cycling remains unknown. Here, we uncover a mechanochemical fatigue process wherein cycling between 173 and 298 K generates irreversible structural injury and deep-level traps through cumulative lattice strain, rather than chemical decomposition. To address this, we design a π-conjugated molecular buffer, (methylsulfonyl)benzamidine (MSMC), which dissipates cumulative lattice strain under cryogenic thermal cycling via a chemical bonding network while simultaneously healing crystallographic defects through bidentate lead coordination. This synergistic strategy endows p-i-n devices that achieve a record efficiency of 28.01% at 228 K (certified 25.94% at 298 K) and, critically, demonstrate unprecedented resilience to cryogenic thermal shocks, retaining 90% of their initial performance after 260 cycles, nearly threefold improvement over controls. The strategy also provides robust compatibility with standard ISOS protocols (light, heat, humidity), underscoring their broad operational resilience. This work establishes mechanochemical fatigue as a fundamental degradation mode and provides a molecular-scale methodology for creating robust photovoltaics suitable for widespread applications.
(Bi0.5Na0.5)TiO3 (BNT)-based ceramics have attracted much attention for energy storage applications, but some fundamental issues remain unclear—in particular, how the conduction mechanism changes with composition and what role oxygen vacancies play. The (0.95−x)[(Bi0.5Na0.5)(1−1.5y)Smy](Zr0.2Ti0.8)O3-0.05BiFeO3-xBa(Sn0.2Ti0.8)O3 (abbreviated as (0.95−x)BNSmZT-0.05BF-xBaSnT, x = 0.05, 0.1, 0.15, 0.2, 0.3, 0.4, y = 0.01) system was investigated, where Ba(Sn0.2Ti0.8)O3 (BaSnT) content varies from 0.05 to 0.4. A non-monotonic conduction transition is revealed by the conductivity and relaxation behavior characterized by impedance spectroscopy and dielectric temperature spectra combined with electric modulus analysis. At low BaSnT (x ≤ 0.1), residual Bi2Ti2O7 at grain boundaries blocks oxygen vacancy migration, giving high activation energy (~2.12 eV) and presenting oxygen vacancy-mediated conduction. At x = 0.15, the impurity disappears and free oxygen vacancies surge, dropping the activation energy to 1.21 eV, corresponding to oxygen-vacancy-dominated ionic conduction with increased carrier density. For x = 0.2–0.4, strong Ba-O-Bi bonds stabilize the migration barrier around 1.57 eV, resulting in mixed oxygen vacancy-mediated conduction. The optimal composition 0.75BNSmZT-0.05BF-0.2BaSnT shows the best dielectric stability and highest resistance. From modulus master curves and broadened M″ peaks, the conduction is identified as correlated hopping of oxygen vacancies, consistent with non-Debye relaxation. This work provides a clear picture of how oxygen vacancy dynamics depend on phase purity, grain boundaries, and A-site chemistry in the BNT-based lead-free ceramics.
Controlling reaction pathways in solids is critical for scalable semiconductor fabrication, yet remains fundamentally challenging in solution-processed systems due to constrained mass transport and diffusion-limited conversion. In perovskite photovoltaics, the widely adopted sequential two-step deposition method is particularly limited by dense PbI2 precursor layers, which impede ion diffusion and lead to incomplete conversion and defect formation. Here we report a photonic strategy to spatially regulate solid-state reaction pathways by engineering micro- and nanoscale channels within PbI2 layers. Laser-induced structures act as deterministic diffusion pathways, enabling controlled ion transport and spatially guided infiltration of organic salts, thereby transforming a diffusion-limited process into a spatially coordinated reaction. Mechanistic investigations reveal that photonic structuring redistributes the local electronic environment and lowers the activation barrier for phase transformation, resulting in accelerated conversion, enhanced crystallinity, and reduced defect density. The resulting perovskite films exhibit improved carrier dynamics. Perovskite solar modules with an aperture area of 22.95 cm2 achieve a record power conversion efficiency of 22.83%, retaining over 90% of their initial performance after 1,500 h under maximum power point tracking. This work establishes photonic control of reaction pathways as a general framework for controlled solid-state transformations.
Poor corrosion resistance and susceptibility to ice accumulation at low temperature significantly limit the application of magnesium (Mg) alloy. It is crucial to develop a durable coating that offers long-term anti-corrosion and anti-icing/deicing properties for the protection of Mg alloy. In this study, a LDH (layered double hydroxide)-PDMS (polydimethylsiloxane)/SO (dimethyl silicone oil) smooth coating with multiple protection function was successfully constructed on the surface of Mg alloy substrate based on the three-level cooperative protection mechanism of "dynamic lubrication layer-static barrier layer-nano oil storage unit". The combined action of PDMS and LDH could form a robust barrier to passively block corrosive media. The SO would form a dynamic lubrication layer at the surface to provide lubrication and dynamic barrier ability. The LDH could also act as the nano oil storage for SO to ensure the stability of lubrication layer. The final coating system showed excellent comprehensive properties such as long-term corrosion protection, anti-icing/deicing, hydrophobicity, self-cleaning and excellent mechanical stability. Due to the excellent barrier effect of the composite coating, it could still provide excellent corrosion protection after immersion in 3.5 wt% NaCl solution for 35 days. After 210 abrasion cycles and 320 tape-peeling cycles, respectively, the surface retained remarkably low ice adhesion strength (tau(ice) < 20 kPa), demonstrating its exceptional mechanical durability. In addition, the LDH-PDMS/SO coating showed good anti-icing/deicing performance at -18 degrees C, outstanding adhesion (5B grade) and self-cleaning properties, and had great application potential in long-term anti-corrosion and anti-icing protection of Mg alloy.
High-voltage output in photovoltaics is crucial for enabling an efficient building-integrated photovoltaic (BIPV) system that integrates hydrogen production, which is a promising strategy for creating green-energy houses and reducing CO2 emissions. This work aims to develop an optimized annealing process in an Ar + S atmosphere for preparing S-rich, low-defect Sb2S3 thin films for high-performance thin-film solar cells. By controlling the heating and cooling rates, the slow heating and rapid cooling (SHRC) process proved optimal, yielding a champion device with a power conversion efficiency of 7.20%, along with an open-circuit voltage (Voc) of 0.803 V, a short-circuit current density of 15.17 mA/cm2, and a fill factor of 59.09%. Notably, we achieved an excellent Voc of 0.807 V, which, to the best of our knowledge, surpasses most previously published Voc values for single-junction Sb2S3 solar cells. Importantly, these SHRC-annealed Sb2S3 solar cells maintain Voc > 0.5 V even under monochromatic LED illumination at a low light intensity of 0.5 mW/cm2. These results demonstrate that an Ar + S atmosphere coupled with a carefully designed annealing profile provides a pathway toward high-voltage-output Sb2S3 thin-film solar cells, enabling BIPV systems to harvest low-intensity "waste" light, such as urban nighttime illumination, for hydrogen production via water splitting.
Currently, photoelectric conversion efficiency (PCE) of perovskite solar cells (PSCs) has reached 27%, yet their industrialization remains constrained by film quality and stability issues in perovskite layers. This study employed butylammonium iodide (BAI) as additive to regulate crystal orientation in perovskite films through retarded crystallization kinetics and induced preferred orientation growth, resulting in significantly enlarged grain sizes and reduced defect densities. Benefiting from the intrinsic high hydrophobicity of organic ammonium salts, optimized films demonstrated enhanced environmental tolerance. Consequently, achieved PCE of rigid devices improved from 22.32% to 23.46% with notably suppressed hysteresis, while that of flexible perovskite solar cells (F-PSCs) improved from 21.51% to 22.26%, confirming the strategy's universality across substrates. Stability tests demonstrated that treatment of perovskite film with BAI led to simultaneous improvements in the environmental stability, thermal stability and light stability of PSCs, as well as the mechanical stability of F-PSCs. This work provides a novel solution for enhancing crystallization control and stability in perovskite films, offering new insights for developing high-performance perovskite photovoltaics with significant industrial application potential.
Moisture-enabled electricity generation (MEG) is an emerging energy-harvesting technology that continuously generates electricity by interacting with ubiquitous ambient water vapor in a pollution-free manner. Its integrable and miniaturizable nature makes it a promising candidate for future scalable and decentralized energy systems. This comprehensive review examines the evolution of MEG devices, focusing on the underlying mechanisms of moisture-material interactions, particularly ion diffusion and streaming potentials. We also provide a detailed analysis of novel carbon-based hygroscopic materials by discussing their types, characteristics, and merits/drawbacks. Finally, we summarize recent advances in MEG applications across various fields.
This study reports the development of a chiral helical soft robot inspired by natural climbing tendrils, fabricated through a low-cost and parameter-tunable approach. Owing to the deep coupling between the intrinsic structure of the material and the thermal field, the system converts ambient thermal energy into kinetic energy without the need for external power sources, thereby exhibiting a unique thermally induced untwisting behavior that generates pronounced initial kinetic energy resulting in a maximum rolling velocity within the upper range of those reported for autonomous robots. The helical LCE strip demonstrates path selection behaviors governed by deformation and energy feedback, enabling remarkable adaptability, self-turning, obstacle avoidance, and obstacle-crossing capabilities in complex environments. Owing to the specific design, an asymmetrical shape can be induced post-fabrication, enabling adaptive control of the self-motion trajectory. The underlying mechanism arises from thermally driven untwisting and energy redistribution; whereby elastic potential energy is stored within the helical architecture during rolling or upon obstacle contact and subsequently released under specific conditions. This work highlights the potential of soft robots for autonomous locomotion, environmental interaction, and the realization of physical intelligence, while offering new strategies for the design of low-power and multifunctional soft robotic systems.
Perovskite light‐emitting diodes (PeLEDs) have demonstrated remarkable potential in the race for next‐generation display technologies due to their outstanding optoelectronic properties. While significant progress is made in improving device efficiency, the device half lifetime (T 50 ) of PeLEDs still falls far short of industrial requirements. Green and red PeLEDs have achieved device half lifetimes on the order of thousands to tens of thousands of hours, whereas blue PeLEDs remain limited to several hundred hours, posing a critical bottleneck to commercialization. In this review, recent advances aimed at extending the device half lifetime of blue PeLEDs are summarized. Also, the key challenges are discussed that hinder the stability of blue‐emitting devices. Finally, a brief outlook and conclusion on future research directions are provided for improving the lifetime of PeLEDs.
Antimony selenide (Sb2Se3) solar cells have attracted considerable attention owing to their excellent optoelectronic properties. However, their efficiency remains severely limited by non-radiative recombination. To address this issue, previous studies have mainly focused on crystal orientation, defect passivation, and interfacial energy-level alignment. Nevertheless, the role of strain in regulating thin-film growth and carrier dynamics has long been overlooked. Here, a heterojunction engineering strategy based on Co2+-doped CdS buffer layers is proposed to regulate lattice strain through tailoring the CdS lattice parameters. Co2+ is found to partially substitute for Cd2+ sites in the CdS lattice. Owing to its smaller ionic radius, Co2+ incorporation induces CdS lattice contraction, thereby reducing the lattice mismatch at the CdS/Sb2Se3 interface, markedly promoting strain relaxation, and improving the growth quality of Sb2Se3 films. Meanwhile, the partial back-diffusion of Co2+ into the Sb2Se3 absorber modulates its crystallization process, promotes preferred orientation, and suppresses defect formation. Moreover, density functional theory calculations combined with experimental characterizations reveal that Co2+ incorporation strengthens interfacial electronic coupling and facilitates charge transfer across the heterojunction. Benefiting from the synergistic effects, the optimized device delivers a champion power conversion efficiency of 9.44%, corresponding to a 16.4% enhancement over the control device.
The transition from lab-scale demonstrations to industrial production of perovskite photovoltaics faces significant challenges in scalability, particularly the persistent area-dependent efficiency loss. Traditional trial-and-error approaches struggle with the multi-dimensional parameter space involving composition, processing, and architecture variations. This study presents a machine learning framework addressing the critical challenge. By analyzing 332 experimental data points through optimized XGBoost models (achieving R2 = 0.8151, RMSE = 1.9699% for PCE prediction), we identify inverted (p-i-n) architectures and Slot-Die coating deposition as optimal for scalability, demonstrating significantly reduced efficiency decay rates compared to formal structures and the other five processes. SHAP analysis reveals the dominant roles of device area, perovskite composition, and device structure in performance optimization. Furthermore, we establish formamidinium-dominant compositions with minimal halide mixing as universally favorable across scaling scenarios. The research provides both fundamental insights into crystallization dynamics and interfacial requirements for large-area fabrication, and practical guidelines for material selection and process optimization, effectively bridging data-driven prediction with experimental development to accelerate the commercialization of perovskite solar modules.
Reversible Zn metal anodes are fundamentally limited by dendritic growth and water-induced parasitic reactions. Herein, we report a nitrogen-rich molecular additive, 1,3,5-triazinan (TA), that enables regulated Zn deposition into an interconnected honeycomb-like two-dimensional (2D) sheet network in aqueous electrolytes. Facet-dependent TA adsorption regulates Zn nucleation, while favorable Zn-adatom migration on Zn(002) facilitates subsequent lateral growth, collectively giving rise to a preferential (002) texture and the distinctive 2D deposition morphology. Meanwhile, TA locally modulates the Zn2+ coordination and hydrogen-bonding environments while strongly interacting with the Zn interface, thereby suppressing water-induced parasitic reactions. TA-derived N-containing species further contribute to a N-rich interphase that stabilizes the electrode/electrolyte interface. As a result, Zn anodes exhibit highly reversible Zn plating/stripping with stable cycling exceeding 1200 h at 2 mA cm−2 1mAh cm−2 in Zn||Zn cells. Furthermore, Zn||V2O5 full cells deliver excellent rate capability and long-term stability, retaining 65 mAh g−1 after 8000 cycles at 5 A g−1. This work provides a molecular-level electrolyte design strategy for controlling metal deposition behavior and advancing practical aqueous zinc-ion batteries.
Antimony selenide (Sb2Se3) has attracted growing interest as a promising thin-film photovoltaic absorber owing to its favorable optoelectronic properties and intrinsic chemical stability. However, device efficiency remains limited by several intrinsic challenges, including quasi-one-dimensional (Q1D) structural constraints that cause ineffective lattice doping, suboptimal crystallinity, high defect density, and unfavorable band alignment at the cadmium sulfide (CdS)/Sb2Se3 heterojunction. Here, we propose a lanthanide doping strategy based on ionic antisite diffusion-using neodymium (Nd3+) to simultaneously engineer bulk crystal growth and interface energetics. By introducing neodymium chloride (NdCl3) onto the CdS surface and exploiting reverse gradient diffusion, Nd3+ ions are effectively incorporated into Sb2Se3 without inducing significant lattice distortion. Meanwhile, the CdS surface is passivated and its roughness reduced, facilitating the deposition of high-quality films. This strategy promotes preferential [hk1] orientation, enhances crystallinity, enlarges grain size, and suppresses deep-level defects. Density functional theory calculations further corroborate the role of Nd in lowering defect formation energies and modulating the electronic structure. Moreover, Nd incorporation optimizes conduction band alignment, suppresses Shockley-Read-Hall recombination, and improves carrier extraction. As a result, the champion device achieves a power conversion efficiency of 9.17%, with a fill factor (FF) of 64.58%, an open-circuit voltage (VOC) of 0.46 V, and a short-circuit current density (JSC) of 30.54 mA/cm2. This work provides fundamental insights into doping in Q1D semiconductors and offers a practical route toward high-efficiency Sb2Se3 photovoltaics.
Dy3+/Tb3+ co-doped (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 ([(Ba0.85Ca0.15)1-x(Dy0.5Tb0.5)x](Zr0.1Ti0.9)O3, abbreviated as x mol% Dy/Tb-BCZT, x = 0.1, 0.5, 1 and 3 mol%) lead-free piezoelectric ceramics were prepared by traditional solid-phase method to acquire outstanding multifunctional performance. Under excitation of 455 nm wavelength light, the x mol% Dy/Tb-BCZT ceramics exhibit energy level transitions of 4F9/2 -> 6H13/2, 6H11/2 (Dy3+), and 5D4 -> 7F5, 7F4 and 7F3 (Tb3+) at 575 nm, 668 nm, and 544 nm, 585 nm and 623 nm, respectively. The ceramics exhibit strong yellow luminescence characteristic and demonstrate significant energy transfer process between Dy and Tb, in which the 4F9/2 -> 6H13/2 energy level transition of Dy3+ presents a magnetic dipole energy level transition, and the 4F9/2 -> 6H11/2 transition presents an electric dipole transition. Dy/Tb-BCZT exhibits the strongest emission peak intensity at x = 1 mol% composition, and presents microsecond magnitude fluorescence lifetime. Large absolute sensitivity SA of 0.407 K-1 and relative sensitivity SR of 0.93 K-1, apparent remnant polarization enhanced fluorescence performance, and excellent piezoelectric fluorescence coupling properties are obtained, indicating that the Dy/Tb co-doped BCZT ceramics possess high application value in the field of fluorescence temperature sensing and are favorable candidate materials for optoelectronic multifunctional ceramic devices.
