The development of nonprecious metals and green hydrogen evolution reaction (HER) electrocatalysts is a major research focus in the context of a two-carbon strategy. In this study, we synthesized a high-efficiency molybdenum phosphide (MoP) catalyst anchored to a porous nitrogen-doped carbon layer (MoP@NC-C3N4) via self-assembly and in situ phosphating processes with a clean phosphorus source (ammonium polyphosphate) and a pore-forming agent (F-108). The electrochemical test results demonstrate that the synthesized MoP@NC-C3N4 catalyst exhibits outstanding catalytic activity and durability in acidic and alkaline environments with overpotentials of 131 and 127 mV and Tafel slopes of 67 and 89 mV & centerdot;dec(-1) (10 mA & centerdot;cm(-2)), respectively. In the catalyst system, g-C3N4 provides both C and N atoms. In addition, the amorphous carbon and MoP nanoparticles exhibit a synergistic effect to promote charge transfer, thereby enhancing catalytic activity. The overpotential of MoP@NC-C3N4 in KOH electrolytes is lower than that of commercial Pt/C at current densities greater than 110 mA & centerdot;cm(-2). This performance provides a valuable reference for potential industrial applications. The density functional theory results indicate that the Mo atom of MoP has the lowest hydrogen adsorption free energy and serves as the optimal catalytic active site for MoP@NC-C3N4. This study paves the way for the design and development of efficient HER electrocatalysts based on graphitic carbon nitrides (g-C3N4).

Double-perovskite Ca2YSbO6 phosphors doped with Dy3+/Sm3+ were prepared by high-temperature solid-state reaction method. The phase structure of the samples was characterized by X-ray diffraction (XRD), and the microscopic morphology, microstructure, luminescence characteristics and energy transfer process of the Ca2YSbO6 phosphor samples were systematically studied by means of scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), fluorescence spectroscopy and lifetime testing. Dy3+/Sm3+ have been incorporated into the Ca2YSbO6 (CYSO) crystal lattice, exhibiting a homogeneous distribution of elements throughout the structure. Ca2YSbO6: Sm3+, Dy3+ phosphors exhibit intense red and yellow emission peaks at 601 nm and 565 nm, respectively. The luminescent performance of Ca2YSbO6: Sm3+, Dy3+ phosphors is the highest when the doping concentrations of Sm3+ and Dy3+ are 0.03 mol and 0.04 mol. By adjusting the Dy3+ concentration and utilizing its energy transfer to Sm3+, tunable emission from orange-red to yellow was achieved for the CYSO: 0.03 mol Sm3+, y mol Dy3+ phosphor. Under 407 nm excitation, the Internal Quantum Efficiency (IQE) of the phosphor is 27.75%. Additionally, Variable-temperature emission spectroscopy further confirmed that the co-doped phosphor has obvious anti-thermal quenching properties. It still has 54.46% of the original luminous intensity at 423 K. The white light-emitting diodes (W-LEDs) demon-strated a high color rendering index (Ra) of 88 and a suitable correlated color temperature (CCT) of 5994 K. These results show that the proposed phosphor has great application potential in supplementing the red-light components of LED lighting.

A new strategy is proposed to construct highly anisotropic conductive hydrogel materials. As a case study, a highly oriented [cobalt ferrite (CoFe2O4)/gelatin (GE)]//[2,7-dibromo-9-fluorenone (DF)/GE] Janus nanobelt is fabricated using parallel electrospinning and polymerization methods, and used as building blocks to construct a photoresponsive luminescent-conductive-magnetic triple function Janus nanobelt hydrogel array membrane (JNHAM). Under light irradiation, JNHAM exhibits anisotropic electrical conductivity, distinctive green luminescence and magnetic properties. When the mass ratio of GE to DF is 1 : 0.2, the degree of anisotropic conductivity of JNHAM is up to 115. In the absence of light irradiation, JNHAM only exhibits magnetic properties. The conversion of the non-anisotropic conductivity to anisotropic conductivity in JNHAM is achieved by utilizing the presence or absence of light. JNHAM responds rapidly to changes in light, temperature, and tensile strain, making it suitable for constructing multi-stimulus-responsive sensors. Changing the presence or absence of light, temperature, load and stress can alter the sensor function and the strength of electrical signals. This sensor can be used for information encryption and transmission. The magnetism of JNHAM can reach 24.68 emu g-1, so it has certain applications in magnetic drive and magnetic anti-counterfeiting fields. JNHAM exhibits significant green luminescence at 522 nm, enabling the visualization study of materials. The design idea and construction technology of this hydrogel solved the technical bottleneck of the complex and difficult construction method of the anisotropic conductive hydrogel. The use of simple materials endows the hydrogel materials with versatility, expands the application range of sensors, and advances the scientific frontier in the field of anisotropic conductive hydrogel materials.

The local charge imbalance caused by hetero-substitution is one of the main reasons for the reduction in the efficiency of luminescent materials. The introduction of charge compensators can effectively neutralize charge imbalance, reduce defect concentration, and enhance the luminescent performance of activator ions. Based on the previous research on Tb3 +/Mn2+ co-doped glass ceramics containing the Y2Sn2O7 crystal phase, this paper innovatively introduces charge compensators to address the charge deficiency issue caused by the heterovalent substitution of Mn2+→Sn4+. Based on density functional theory, the occupation trends of different charge compensators were first simulated, and Mo6+ was selected as the compensating ion. The addition of Mo6+ caused the red emission peak of Mn2+ to shift by 12 nm to the red, resulting in more significant chromatic coordinate changes in the Tb³ ⁺-Mn²⁺-Mo⁶⁺ co-doped glass-ceramic samples within the temperature range of 298 K to 473 K. The temperature sensing performance was improved, with the maximum absolute sensitivity reaching 4.25 × 10−2 K−1 and the maximum relative sensitivity reaching 4.78% K−1. This study combines theoretical calculations with experimental verification, providing a new reference basis for the selection of charge compensators and demonstrating the application potential of this material in optical temperature sensing.

High-performance phosphors play a crucial role in the advancement of high-quality lighting; however, significant challenges remain in optimizing phosphor luminescence performance. In this study, we present a novel samarium ion-doped red phosphor (Y10W2O21: Sm3+) synthesized for the first time using a high-temperature solid-phase reaction method. We systematically investigated its crystal structure, morphology, luminescence properties, decay time, and thermal stability. Cationic substitution (Al-Y) is employed to enhance the optical properties of the phosphors. Comparison of the performance of the phosphors before and after Al doping showed that the luminescence intensity was significantly enhanced by partially replacing Y3+ with Al3+ and composition tuning of the Y10W2O21:Sm3+ phosphor, a strong orange-red emission is produced at 606 nm. This improvement can be further elucidated by discussing the enhancement of luminescence resulting from Al3+ substitution, considering the crystal field effect at the Sm3+ center and the structural changes occurring in the phosphors, and its internal quantum efficiency was measured to be 30.12 %. Finally, Y10W2O21: 0.02Sm3+; 0.03Al3+ were combined with commercially available phosphors (BaMaAl12O10:Eu2+ and BaSr2SiO4:Eu2+) to fabricate a warm white light-emitting diodes (WLED) device with a color reproduction index (Ra) of up to 90.4 and a color temperature of 4627 K on a chip at 395 nm, which realized full-spectrum illumination. Potential application prospects are demonstrated.

Oil shale ash (OSA) and phosphorus slag (PS) are combined to prepare glass ceramics for the first time, achieving clean utilization of solid waste. In this work, glass ceramics are prepared using high-temperature melting method with OSA residue and PS residue as the main raw materials, TiO2 as the nucleating agent. The CaO provided by PS can improve the crystallinity of glass prepared from OSA as raw material. The microstructure, crystal phase, properties, and heavy metal immobilization mechanism of glass ceramics with different OSA/PS mass ratios are studied. The results showed that the crystal phase of the glass ceramic is KNa3Al4Si4O16, with a maximum density of 2.830 g/cm3, a minimum water absorption rate of 0.0067 %, a maximum Vickers hardness of 842 HV, and acid and alkali corrosion resistance greater than 96.69 % and 99.9 %, respectively. Glass-ceramics have a good curing effect on metals such as Pb2+, Cr3+, Cu2+, Zn2+ and Fe3+, and the leaching concentrations are 0.4818 mg/L, 1.3995 mg/L, 0.6401 mg/L, 0.3624 mg/L, and 2.0736 mg/L, respectively. At the same time, the impact of heavy metals in glass ceramics on the environment is evaluated through wheat seed germination experiments, which further demonstrated the environmental safety and potential application feasibility of glass-ceramics. This study not only achieved low-carbon, green and clean utilization of OSA and PS, but also prepared high value-added building decoration materials. The development of green building materials has promoted energy conservation and emission reduction, and propelled the construction industry towards green, low-carbon, and sustainable development. This work provides theoretical guidance for the clean utilization of solid waste and the development of green building materials.

A new strategy to substantially increase the degree of anisotropic conductivity of hydrogel materials and a new technique to establish the universal construction of multifunctional highly anisotropic conductive hydrogel materials are proposed. The highly oriented [double network]//[single network] Janus nanobelts viz. [Tb (TTA)3(TPPO)2/gelatin (GE)]//[polyaniline (PANI)/GE] Janus nanobelts used as building units are fabricated by parallel electrospinning technology, and the anisotropic conductive-luminescence double-functional Janus nanobelt hydrogel array membrane (recorded as JAHM) is constructed. Using Janus structure as the building unit avoids adverse interactions between conductive and luminescent materials, resulting in excellent green luminescence and high conductivity of JAHM. The conductive side of Janus nanobelt is further cleverly designed as a double network structure with physical cross-linking of PANI and GE chains, which is linked by hydrogen bonding to increase the water content and conductivity, and thus improve the degree of anisotropic conductivity, the insulating side of Janus nanobelt is GE single network structure containing Tb(TTA)3(TPPO)2. The integration of hydrogel single and double network structures is realized in Janus nanobelt and the degree of anisotropic conductivity of JAHM is up to 2.41 x 105. Compared with the reported anisotropic conductive hydrogel, the anisotropic conductivity of JAHM is significantly improved, and the preparation method is simple, which solves the complex problem of complicated preparation method of traditional anisotropic hydrogels. JAHM responded rapidly at different tensile strains and different temperatures, and the assembled strain sensors are sensitive to human joint motion detection (gauge factor of 4.24). This project can help to provide new routes and technical support for the improvement of the anisotropic conductivity of hydrogel materials, and lay the foundation for the development of other multifunctional conductive hydrogel materials.

In this study, Eu3+-doped borate glass (ZBSS) is developed to systematically investigate the impact of Eu3+ concentration on the structure, optical properties, and luminescent performance of the glass. According to the investigative results, the incorporation of Eu3+ significantly increases the glass density (2.8948-2.9535 g/cm3) by replacing low-molar-mass B2O3, with non-bridging oxygens (NBOs) formed. This facilitates the densification of the glass network structure, substantially improving refractive index (1.5459-1.5527). Additionally, FTIR and XRD analyses reveal the structural change from BO3 to BO4 units and the unique role of Eu3+ as a network modifier. According to a further analysis based on Judd-Ofelt theory, the 0.9 mol% Eu3+-doped sample (ZBSS-5) exhibits the optimal luminescent properties, with an impressive Omega 2 parameter of 4.66 x 10-20 cm2 and a high quantum efficiency of 78 %. Moreover, this sample has a maximum gain bandwidth of 163.709 x 10-28 cm3 at 614 nm, which is attributed to the significant enhancement of the 5D0 -> 7F2 electric dipole transition. As confirmed by temperature-dependent experiments, the glass possesses a high thermal stability, maintaining a luminescence of up to 473 K at a low activation energy of 0.2836 eV. To sum up, this study proposes a highperformance glass material for developing high-brightness red lasers and optoelectronic devices.

The NaCl:xEu3+ (x = 0.002, 0.004, 0.006, 0.008, 0.01, 0.02) ceramics were synthesized using a cold sintering method under varying temperature and pressure conditions. The impact of Eu3+ ions on the structural and optical properties of NaCl ceramics was examined by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), analytical scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), UV-visible spectroscopy, reflectance spectroscopy, photoluminescence (PL) spectroscopy, and fluorescence lifetime measurements. XRD analyses confirmed the incorporation of Eu ions into the matrix lattice. SEM results indicated that the ceramics achieved high density when the uniaxial pressure exceeded 300 MPa. EDS analysis demonstrated a well-distributed presence of rare earth ions, devoid of impurities. PL spectroscopy revealed that the intensity of the emission spectra increased the increase of Eu3+ concentration and observed the optimal luminescence performance at x = 0.01 mol% and a sintering temperature of 125 degrees C. XPS results indicated that the Eu ions were predominantly in a trivalent state within the NaCl ceramics. Collectively, the above results provide valuable insights for the preparation of rare-earth doped alkali halide ceramics using cold sintering technology.

Further trying its optical performance, CeF3 single crystal has very high transmittance of 90 %, the cut-off absorption edge length of the crystal is better than 300 nm.

A series of Tb3+ ions doped sodium magnesium aluminum borosilicate glasses 15Na(2)O-15MgO-15Al(2)O(3)-20SiO(2)-35B(2)O(3) (abbreviated as NMASB):xTb(3+) (x = 0, 0.2, 0.6, 0.8, 1, 1.5 and 2 %) were prepared by the high-temperature melting method. The structural properties of the glass were explored by analyzing the results of X-ray diffractometer (XRD), infrared and Raman spectra. The Delta T value of Differential scanning calorimeter (DSC) showed good thermal stability of the glass. The optical properties of the glass were studied by absorption spectroscopy, photoluminescence (PL) spectroscopy, CIE chromaticity color temperature, fluorescence decay curve, quantum efficiency and thermoluminescence (TL) curve. The absorption spectrum owned four absorption peaks at 351, 368, 377 and 485 nm, and the optical band gap of the glass with different Tb3+ concentrations was from 3.37 to 3.27 eV. Under the excitation at 377 nm, the NMASB:Tb-\ glass showed several sharp emission peaks centered at 485, 543, 582 and 622 nm, corresponding to the transitions of D-5(4) -> F-7(n) (n = 6, 5, 4, 3), respectively. The fluorescence lifetime was fitted by the three-exponential function ranged from 2.89 ms for NMASB:0.2%Tb3+ to 2.66 ms for NMASB:2%Tb3+, indicating that the glass had high charge separation efficiency. Judd-Ofelt theory was used to fit the intensity parameters Omega(i) (i = 2,4,6), and the absorption oscillator strengths, spectral quality factors, spontaneous transition probabilities, and fluorescence branching ratios of the optical transitions were calculated. The TL curves of pure and Tb-doped glasses both owned two peaks, indicating that there were two different depths of traps in the glass. The luminescence intensity was greatly improved after Tb doping, and the TL intensity of the glass was linearly related to the dose. These results indicate that Tb-doped NMASB glass can be a potential material for blue-green laser and thermoluminescence dosimeter(TLD) applications.

The CIE chrominance coordinate diagram determines that the chrominance coordinate value is close to the standard white light, the correlation color temperature calculation proves that it is located in the cold white light region. The decay curve can be fitted with the double exponential attenuation equation. The above results show that Dy 3 + doped niobiosilicate glass has the potential to be used as W -LED material.

SiO2-B2O3-GdF3-CaO-Bi2O3 doped glasses containing Er3+/Yb3+ ions at varying concentrations were successfully synthesized using a high-temperature melting method. The glass samples' physicochemical properties and amorphous structure were characterized through density, XRD, XPS, FT-IR, and Raman analyses. Thermal expansion coefficient testing indicated good thermal stability of the glass system. Increasing the Yb3+ doping concentration enhanced near-infrared luminescence at 1.53 mu m, with maximum luminescence intensity at approximately 3.2 mol% doping concentration. The energy transfer mechanism of Er3+/Yb3+ doped SiO2-B2O3-GdF3-CaO-Bi2O3 glass was elucidated through fluorescence spectrum analysis, revealing J-O parameters Omega(2) = 11.2 x 10(-20) cm(2), Omega(4) = 8.9 x 10(-20) cm(2), and Omega(6) = 9.59 x 10(-20) cm(2). Calculations for absorption cross-section, cross-section of emission, and gain curve additionally reinforced the glass's capability for laser uses.

In this paper, Sr2SiO4 phosphors with different Sm3+ concentrations and Sr2SiO4:0.006Sm3+ phosphors obtained from the coal gasification slag as raw materials have been synthesized by the high-temperature solid-phase method. The influence of Sm3+ ions and the purity of SiO2 on the structural and optical attributes of Sr2SiO4 have been investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible (UV-Vis) spectrum, photoluminescence (PL) spectra and fluorescence lifetime analysis. XRD results showed that the doping ions have entered into the host lattice, and SEM shown the crystallite sizes have been found to vary from 1 to 3 mu m. PL spectra displayed that the emission intensity of the samples increased with the increase in concentrations of Sm3+ ions. At the optimum doping concentration, the luminous intensity and fluorescence lifetime of the sample prepared by the purified silica is much higher than that of the phosphor prepared by the chemical product silica, which is close to that of the pure chemical reagent. Finally, we explored the application of fluorescent powder in pc-WLED devices. Notably, the devices exhibited excellent luminous performance at 20 mA current. The results demonstrate that coal gasification slag (CGS) product can be used to synthesize brilliant materials with potential uses for the pc-WLED technology.

Increase in Dy3+ concentration is found to decrease the optical band gap; the calculated Judd-Oflet parameter is found to follow the trend Omega(2)>Omega(4)>Omega(6). Photoluminescence studies have shown three emission peaks which could be associated to the transitions: F-4(9/2) -> H-6(15/2) (blue light), F-4(9/2) -> H-6(13/2) (yellow light), and F-4(9/2) -> H-6(11/2) (red light); the maximum intensity obtained for the glass with x = 0.75 mol%, with spacing between Dy3+ ions being 1.9137 & Aring;; and the decay curve could be fitted with double exponential function. The CIE results have revealed that the chromaticity coordinates are closer to that of standard white light, and the color temperature located in the region of cold white light.

The commercial LED has the disadvantages of low thermal stability and poor luminous quality at high temperature due to the organic resin encapsulation phosphor, and luminous glass is one of the effective ways to solve this problem. A series of niobium silicate (SiO2-Nb2O5-Na2O-K2O-Dy2O3-Sm2O3, labeled as SNNKDS) luminous glasses have been obtained by melt quenching method. The results of differential thermal analysis prove the existence of high thermal stability. The infrared spectrum, Raman spectrum and the calculation of physical parameters reveal the excellent thermal stability and stable structure of the prepared glass. The optical properties of luminescent glass have been studied in detail, the energy transfer from Dy3+ ions to Sm3+ ions has been observed, the Dy3+/Sm3+ co-doping glasses can achieve warm white light emission by changing the excitation wavelength and the doping amount of Sm3+. The variable temperature emission spectrum of SNNK:0.8D0.4S is analyzed. At 423 K, the comprehensive emission intensity is 79.91% of that at room temperature, the ΔC value of colorimetric shift at 473 K is 2.1×10-2. The warm white light output with excellent correlated color temperature (3746 K) has been achieved using glass samples encapsulated with 395nm LED chip.

This study successfully grew KBaY(MoO4)3 crystals doped with single Er3+ ions and co-doped with Ca2+/Er3+ ions using the top-seeded solution growth method. Thermal analysis of the KBaY(MoO4)3 crystals was performed by differential scanning calorimetry, and their phase and structure were characterized using X-ray diffraction and Fourier transform infrared spectroscopy. The luminescent properties of the crystals in the visible and nearinfrared wavelength ranges under different concentrations of Er3+ ions were analyzed through emission spectroscopy, and the concentration quenching mechanism was investigated in depth. The results showed that the strongest emission intensity was obtained at an Er3+ ion concentration of 5 mol%. Additionally, by substituting Ba2+ ions with Ca2+ ions, the emission intensity was significantly enhanced, especially when the Ca2+ ion doping concentration reached 6 mol%, resulting in the maximum emission intensity. Furthermore, we investigated the effects of matrix structure and lattice distortion on the spectral properties by employing Judd-Ofelt (J-O) theory and studying energy transfer mechanisms. The mechanisms of Ca2+-induced fluorescence quenching and factors influencing the fluorescence decay time were analyzed. Through the analysis of the absorption cross-section, emission cross-section, and gain cross-section of crystals with different Ca2+ ion concentrations, it was found that Ca2+, Er3+: KBYM crystals exhibited a low laser pump threshold. The results demonstrate that the 6 mol% Ca2+, 5 mol% Er3+: KBYM crystals possess excellent performance and are a promising laser gain medium.

Niobium silicate based materials have become a research focus due to their interesting photoelectric properties. In this study, a series of 35SiO2-35Nb2O5-10Na2O-20K2O-xSm2O3 (with x = 0.2/0.4/0.6/0.8/1.0/1.2 mol%) luminous glasses were prepared and characterized. Presence of Si-O-Si and O-Nb-O bonds makes these glass samples to have extremely high thermal stability; and addition of alkali metal ions increases their disorder. The lower optical bandgap and higher Urbach energies obtained prove that it is conducive to the microenvironment of luminescence. They exhibit strong absorption in the ultraviolet region and small chromaticity shift at high temperature. Glass with x = 0.8 mol% has been found to have the highest emission intensity, 84.85% transmittance, and 98.83% color purity, which proves the feasibility of the prepared luminous glass as the red light composition of LED. Concentration quenching can be associated mainly to the nearest neighbor ion interaction; increase of Sm3+ concentration causes decreasing distance of luminescent ions. The temperature range of 298-423 K shows promising application potential in optical temperature measurement, with maximum absolute sensitivity of 0.521% K-1 and maximum relative sensitivity of 0.550% K-1 being observed. Unique properties observed for the Sm3+ doped niobium silicate glasses indicate their development value in the field of multifunctional materials.
