A 40Bi2O3–30Li2O–15B2O3–7CuO–5TeO2–3MoO3 glass was synthesized by melt-quenching at 1200°C to investigate its structural, thermal, dielectric, and basic physical properties as a Bi2O3-rich oxide glass with potential relevance to thermoelectric research. Density and molar volume determined by Archimedes’ method were 4.63 g cm–3 and 48.28 cm3 mol–1, respectively, indicating a relatively compact glass network influenced by heavy metal oxides. X-ray diffraction confirmed the amorphous nature of the sample. Fourier-transform infrared spectra revealed vibrations associated with BO3 and BO4 units and borate-related species (including metaborate- and pyroborate-type units), consistent with a borate-based network modified by Bi2O3, CuO, and TeO2; however, boroxol rings cannot be assigned unambiguously from the present spectra. Differential scanning calorimetry conducted between room temperature and 650°C showed a glass transition near 420°C and no strong crystallization peak in this range, indicating good thermal stability at moderate temperatures. The dielectric response, measured between 100 Hz and 1 MHz, exhibited high capacitance and permittivity at low frequencies, followed by a marked decrease with increasing frequency, which can be attributed to the progressive freezing of ionic and interfacial polarization and is consistent with Maxwell-Wagner type behaviour. These results provide baseline information on the structure, thermal behaviour, and dielectric properties of this Bi2O3-rich glass composition and indicate that further work, including direct measurements of electrical resistivity, Seebeck coefficient, and thermal conductivity, is required before its thermoelectric performance can be fully assessed.

This study investigates the physical, structural, optical, and luminescence properties of erbiumdoped boro-tellurite zinc niobium barium (ErBT) glass. The glass was characterized by exploring the impact of erbium doping on its physical, structural, optical, and luminescence behavior. The density, molar volume, and refractive index describe the physical properties, ranging from 3.73 to 4.11 g/cm(3), 33.82 to 36.47 cm(3)/mol, and 1.72 to 1.79, respectively. Structural analysis, utilizing techniques such as X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR), reveals that the glass network is amorphous, and the vibrations of the molecules determine the internal structure of the glass. Optical properties were examined through absorption spectroscopy, providing insights into the energy levels of 4f from the 4I15/2 ground state to various excited states, such as (4)F5/2, (4)F7/2, (2)H11/2, (4)S3/2, (4)F9/2, (4)I9/2, (4)I11/2 and( 4)I13/2. These transitions are positioned at wavelengths of 450, 487, 532, 541, 655, 799, 980, and 1535 nm, respectively. Moreover, NIR luminescence measurements were performed to evaluate the luminescence behavior of the erbium-doped glass, which shows state-level energy can be assigned to the (4)I13/2 -> (4)I15/2 transition at 1535 nm, emission properties, and potential applications. The results demonstrated the modification of the ErBT glass's optical behavior and the enhancement of its luminescence characteristics through the doping of erbium. These results contribute to the fundamental understanding of erbium-doped glasses and provide guidelines for applications in optoelectronics, lasers, and optical amplifiers. Further exploration in this field has the potential to novel applications and optimize the performance of erbium-doped ErBT glass in various photonic devices.

Samarium-doped glasses have attracted considerable interest due to their promising optical properties for use in photonic, laser, and optoelectronic applications. In this work, a comparative study was conducted on Sm³⁺-doped borotellurite glasses with the chemical composition 29TeO₂–30B₂O₃–10X–20BaO–10Nb₂O₅–1Sm₂O₃, where X represents either ZnO or ZnF₂. The influence of the modifier type (oxide vs. fluoride) on the structural and luminescence behavior of the glasses was thoroughly examined. The incorporation of Sm³⁺ ions into these host matrices leads to significant variations in optical performance, dictated by the local environment and bonding characteristics. Comprehensive characterization, including absorption and emission spectra, and luminescence lifetimes, was performed to evaluate the suitability of each glass system for optical device applications. The findings highlight the critical role of glass composition in tailoring the emission efficiency and optical response of rare-earth-doped glass materials.

This study explores the properties of Holmium-doped phospho-tellurite glass, with varying concentrations of Ho2O3, measuring the physical, structural, optical, and luminescence characteristics of the glass. Physical properties including density, molar volume, and refractive index are measured and analyzed. XRD is used to confirm the amorphous nature of the glass for structural properties, while FTIR is used to confirm bonding in the glass system. Absorption and luminescence are measured within the wavelength range of 200 - 2000 nm and 400 - 750 nm, respectively. The obtained spectra were analyzed using the Judd-Ofelt theory, which provides insights into the energy levels of Ho3+ ion doped in the phospho-tellurite glass matrix. Notably, our analysis of the spectral line corresponding to the 5F4 → 5I8 transition (~ 529.0 nm), showcases a highly stimulated emission cross-section. The calculated oscillator strength, Judd-Ofelt intensity parameters, branching ratio, and other parameters further elucidate the potential of Ho3+ ion doped phospho-tellurite glass for efficient laser emission in this glass system.

The Sr2ZnMoO6 phosphor was incorporated into TeO2: ZnO: BaO glass using the microwave synthesis, with different amount of phoshors (0.00, 2.50, 5.00, 7.50, and 10.00 wt%). The samples were characterized through density, refractive index, XRD, FTIR, absorption spectra, luminescence properties, and lifetime analysis. The crystalline structure was analyzed by using X-ray diffractometer and compared with the standard Sr2ZnMoO6 crystal structure. Absorption spectra analysis showed four peaks associated with the transitions of Eu3+ ion, while photoluminescence was observed between 550 and 725 nm when excited at 465 nm.

These samples exhibited a high photoluminescence quantum yield of 56.49%, with the high-intensity peak observed at 614 nm, corresponding to the 5D2 → 7F0 (reddish orange) transitions of Eu3+ ion. The luminescence lifetime values from the 5D2 → 7F0 state decreased (0.891, 0.886, 0.880, and 0.874 ms) by adding a concentration of phosphors, The results indicate that these samples have the potential to be used in solid-state lighting applications.

Rare-earth doped glasses have gained significant attention due to their potential applications in photonic devices, including scintillators and thermoluminescence dosimeters (TLD). Among these, terbium (Tb3+) ion is known for their strong green luminescence, making them valuable for optical and radiation detection technologies. The combination of TeO2 and other glass modifiers enhances the optical and structural properties of the host matrix, making it suitable for doping with rare-earth ions. The primary goal of this study is to synthesize and characterize a series of Tb3+ doped tellurite-based glasses with varying concentrations of terbium oxide (Tb2O3) for scintillation and thermoluminescence material application. Glasses with the molar composition (30-x) TeO2: 20B2O3: 20MgO: 10Li2O: 10Al2O3: 10La2O3: xTb2O3 (x is 0.0, 1.0, 2.0, 3.0, 4.0 and 5.0 mol%) were produced using a conventional melt-quenching approach. X-ray diffraction analysis confirmed that the glass was amorphous. In addition, the UV-VIS-NIR spectrometer recorded the absorption spectra of a number of peak values. As the concentrations of Tb3+ increase, both the radioluminescence (RL) and photoluminescence (PL) results increase. The glass samples exhibited strong luminescence spectra with prominent emission bands at 545 nm, corresponding to the characteristic transitions of Tb3+ ion. The highest luminescence efficiency of Tb3+ ion was observed at a concentration of 4 mol%. In the prepared glasses, the RL and PL obtained from different concentrations of Tb3+ ion is almost close to the green light region, as shown in the CIE 1931 chromaticity diagram. Furthermore, the thermoluminescence (TL) parameters were calculated using Chen is peak shape method, such as activation energy (E) and frequency factor (S). The developed glasses show promise for use in Scintillation and TLD.

AMoRE searches for the neutrinoless double beta decay using 100 kg of enriched ^{100}Mo. Scintillating molybdate crystals coupled with a metallic magnetic calorimeter operate at milli-Kelvin temperatures to measure the energy of electrons emitted in the decay. AMoRE-I is a demonstrator for the full-scale AMoRE, operated at the Yangyang Underground Laboratory for over two years. The exposure was 8.02  kg year (or 3.89  kg_{^{100}Mo} year), and the total background rate near the Q value was 0.025±0.002  counts/keV/kg/year. We observed no indication of 0νββ decay and report a new lower limit of the half-life of ^{100}Mo 0νββ decay as T_{1/2}^{0ν}>2.9×10^{24}  yr at 90% confidence level. The effective Majorana mass limit range is m_{ββ}<(210-610)  meV using nuclear matrix elements estimated in the framework of different models, including the recent shell model calculations.

The Sr(1-x)TeO3:xEu2O3 phosphors were synthesized using the conventional high-temperature solid-state reaction method at 800°C for 3 h in air atomosphere. The assynthesized phosphors were characterizated using XRD, FTIR, absorption spectra, photoluminescence, and X-ray-induced luminescence. Rigaku SmartLab-SE XRD diffractometers confirmed the crystalline nature of the phosphors. From the study, it was found that the structure of the sample was a mixture of SrTeO3 and TeO2. The increased concentration of Eu2O3 seems to contribute to the enhancement or stabilization of SrTeO3 phase. The UV-VIS-NIR spectrophotometer in reflection mode measured the absorption spectrum, revealing six peaks corresponding to energy transitions of Eu3+ ions at 394, 465, 536, 592, 2,207, and 2,070 nm. Photoluminescence analysis demonstrated the strongest luminescence intensity of Eu3+ ions at 614 nm (7F2) under 465 nm excitation, resulting in an overall red emission in the CIE 1931 chromaticity. Combining these findings, Sr(1-x)TeO3: xEu phosphors exhibit promising characteristics for solid-state lighting applications (SSL). The X-ray-induced luminescence shows an increase with increasing concentrations of Eu2O3 until 0.10%. The samples with the maximum intensity were compared with bismuth germanate oxide (BGO) crystals, which are used as radiation detectors, and were found to be as effective as 33.65% of the BGO crystals. The results demonstrate that the current samples could be a potential candidate for use in scintillator applications.

This study presents the development of boro-tellurite glasses doped with varying concentrations of Dy2O3 (0.0, 0.1, 0.5, 1.0, and 1.5 mol%) using a conventional melt-quenching technique, targeting advanced thermoluminescence materials for radiation detection. Structural characterization via X-ray diffraction confirmed the amorphous nature of all samples, while comprehensive optical investigations-including UV-Vis-NIR absorption and photoluminescence spectroscopy-revealed distinct intra-4f electronic transitions of Dy3+ ions. The incorporation of Dy2O3 not only altered the optical absorption and emission characteristics (exhibiting prominent blue and yellow bands) but also significantly modified the glass network, influencing density, molar volume, and the formation of defect-related electron traps. Thermoluminescence measurements, performed under controlled irradiation with an Am-241 source at a dose of 1 mGy and a heating rate of 5 degrees C/s, exhibited a welldefined glow peak whose intensity and activation energy were strongly dependent on the Dy concentration. An optimal performance was observed at 1.0 mol% Dy2O3, where the activation energy peaked at 1.17 eV, indicative of deep and stable traps favorable for dosimeter applications. These results demonstrate that precise control of Dy2O3 doping in boro-tellurite glasses can significantly enhance their performance, making them promising candidates for reliable radiation dosimetry in medical.

he glasses prepared with praseodymium oxide (Pr2O3) in phosphor-tellurite glass systems with varying compositions were used to study their emission behavior. The compositions investigated range from the base glass (40-x)TeO2 - 30P2O5 - 20ZnO - 10Sb2O3 to the glass with the addition of praseodymium oxide at different concentrations, represented by the parameter x. The main objective of this research was to understand the influence of praseodymium oxide on the optical and spectroscopic properties of the glass matrices. The glass samples were prepared using conventional melt-quenching techniques at 1100°C for 30 min, annealing at 300°C for 3 h, and characterization using various analytical methods. Changes in physical properties of the glass due to the addition of praseodymium were recorded and analyzed. It was observed that the addition of praseodymium decreased densities from 4.15 to 3.90 g/cm3, and refractive index from 1.653 to 1.633. However, the molar volume increased from 36.5 to 39.2 cm3/mol. The existence of the glass host (phospho-tellurite) and its physical characteristics were confirmed by FTIR and XRD analysis. Optical absorption spectra were recorded to investigate the peaks associated with transitions from 3H4 state to 3P2,1,0, 1D2, 1G4, and 3F4,3,2 states. Photoluminescence (PL) spectra were measured to study the emission characteristics, including the emission peaks (3P0 → 3H4, 3P1 →3H5, 1D2 → 3H4, 3P0 →3F2, and 3P1 →3F3). At concentrations above 0.1 mol % of Pr3+ ions, the emission intensities are found to decrease with the increase of Pr3+ concentration due to concentration quenching. Additionally, the CIE chromaticity coordinates, ranging from orange to green, were determined to assess the suitability of glasses for visible luminescence devices.

Abstract The AMoRE collaboration searches for neutrinoless double beta decay of $$^{100}$$ 100 Mo using molybdate scintillating crystals via low temperature thermal calorimetric detection. The early phases of the experiment, AMoRE-pilot and AMoRE-I, have demonstrated competitive discovery potential. Presently, the AMoRE-II experiment, featuring a large detector array with about 90 kg of $$^{100}$$ 100 Mo isotope, is under construction. This paper discusses the baseline design and characterization of the lithium molybdate cryogenic calorimeters to be used in the AMoRE-II detector modules. The results from prototype setups that incorporate new housing structures and two different crystal masses (316 g and 517–521 g), operated at 10 mK temperature, show energy resolutions (FWHM) of 7.55–8.82 keV at the 2.615 MeV $$^{208}$$ 208 Tl $$\gamma $$ γ line and effective light detection of 0.79–0.96 keV/MeV. The simultaneous heat and light detection enables clear separation of alpha particles with a discrimination power of 12.37–19.50 at the energy region around $$^{6}$$ 6 Li $$(n,\alpha )^3$$ ( n , α ) 3 H with Q-value = 4.785 MeV. Promising detector performances were demonstrated at temperatures as high as 30 mK, which relaxes the temperature constraints for operating the large AMoRE-II array.

This study conducts an extensive examination of the TeO2-P2O5-Sb2O3-ZnO-Sm2O3 glass composition, with a central focus on physical, structural, optical, and luminescence properties. The optical properties of Sm3+ ions were investigated by the absorption spectrum from the ground state H-6(5/2) to various excited states. The absorption spectra clearly revealed seven bands, with peaks at 972 nm, 1073 nm, 1222 nm, 1365 nm, 1468 nm, 1520 nm, and 1586 nm. These bands correspond to changes that correspond to energy levels F-6(11/2), F-6(9/2), 6 6F F-6(7/2,) F-6(5/2) , F-6(3/2), H-6(15/2) , and F-6(1/2 , ) respectively. Examining the luminescence properties of the glass appears a luminescence spectra characterized by four prominent peaks. These peaks are distinctly attributed to the (4)G(5/2) -> (6)H(s )transitions, where s assumes values of 5/2, 7/2, 9/2, and 11/2, manifesting at wavelengths of 566 nm, 602 nm, 649 nm, and 708 nm, respectively. An interesting finding was the incorporation of Sm2O3 doped into the glass matrix at a concentration of 1 mol%, which produced an interesting quenching effect in the luminescence spectra. This quenching effect assumes paramount significance and catalyzes a comprehensive exploration of the Judd-Ofelt values. The values obtained through this analysis are pivotal in evaluating the potential of this glass composition for laser applications.

In this study, the physical and thermoelectric characteristics of glass-ceramic materials are examined to provide the thermoelectric performance of 30Li2O: 3MoO3: 40Bi2O3: 20TeO2: 7CuO samples that were synthesized utilizing the melt-quenching process. Archimedes' Principle was used to determine the physical properties of the sample, showing a density of 4.53 g/cm3. An X-ray diffractometer (XRD) used to analyze the crystal structure revealed the Bismuth Oxide phase. The results of measuring with the LCR Meter for the frequency range were set from 50 Hz to 1 MHz at room temperature, showing the dielectric constant (ε’) and the dielectric loss (ε”) that tended to decrease with increasing frequency. Thermoelectric properties were examined in a temperature range of 300 K to 600 K indicating the electrical resistivity, the Seebeck coefficient, and the power factor. By calculating the efficiency of thermoelectric materials, the power factor term is considered at which temperature it shows its highest value. In this work, it was shown on 6.99 mW/mK2 at a temperature of 474 K

A series of glass samples, with base composition of (40-x) TeO2: 30B2O3: 20ZnO: 10Li2O, was modified by incorporating varying concentrations of Sm2O3 (x = 0.00, 0.10, 0.50, 1.00, 1.50, and 2.00 mol%). X-ray diffraction analysis confirmed the amorphous nature of the prepared glasses. FTIR spectroscopy was used to investigate the structural arrangement of the glasses, revealing characteristic vibrational bands associated with Te-O, B-O, and Zn-O bonds. These bands provided insights into the glass network's evolution with changing Sm2O3 content. The optical properties of the glasses were investigated through absorption and photoluminescence studies. Absorption spectra, measured in the 400-1800 nm range, displayed seven peaks attributed to electronic transitions within the Sm3+ ion. These transitions originated from the 6H5/2 ground state to various excited states. Photoluminescence analysis, excited at 403 nm, revealed a strong emission band centered at 597 nm. This emission corresponded to the 4G5/2 → 6H7/2 transition of Sm3+, responsible for the characteristic orange luminescence. The emission intensity increased with increasing Sm2O3 concentration up to 1.00 mol%, after which concentration quenching led to a decrease in intensity. In conclusion, this study elucidates the composition-structure-property relationships in Sm2O3-doped TeO2-B2O3-ZnO-Li2O glasses. The tunable orange emission suggests their potential as phosphors for solid-state lighting applications, particularly in orange LEDs.

AbstractAMoRE-II aims to search for neutrinoless double beta decay ($$0\nu \beta \beta $$ 0 ν β β ) with an array of 423 $$\hbox {Li}_2^{100}\hbox {MoO}_4$$ Li 2 100 MoO 4 crystals operating in the cryogenic system as the main phase of the Advanced Molybdenum-based Rare process Experiment (AMoRE). AMoRE has been planned to operate in three phases: AMoRE-pilot, AMoRE-I, and AMoRE-II. AMoRE-II is currently being installed at the Yemi Underground Laboratory, located approximately 1000 m deep in Jeongseon, Korea. The goal of the experiment is to reach an exclusion half-life sensitivity to the $$0\nu \beta \beta $$ 0 ν β β of $$^{100}$$ 100 Mo on the level of $$T^{0\nu \beta \beta }_{1/2} > 6 \times 10^{26}$$ T 1 / 2 0 ν β β > 6 × 10 26 year that covers completely the inverted Majorana neutrino mass hierarchy region of (15–46) meV. To achieve this, the background level of the experimental configurations and possible background sources of gamma and beta events should be well understood. We have intensively performed Monte Carlo simulations using the GEANT4 toolkit in all the experimental configurations with potential sources. We report the estimated background level that meets the $$10^{-4}$$ 10 - 4 counts/(keV$$\cdot $$ · kg$$\cdot $$ · year) requirement for AMoRE-II in the Region Of Interest (ROI) and show the projected half-life sensitivity based on the simulation study.

Era(3+)-doped phospho-tellurite glasses were synthesized via the melt-quenching technique and investigated for their structural and optical properties. XRD confirmed the amorphous nature, while FTIR spectra revealed characteristic vibrational modes associated with P-O and Te-O bonds. The optical absorption spectra exhibited multiple 4f-4f transitions of Era(3+ )ions, with a prominent band at 1536 nm corresponding to the 4I(13 & frasl;2) -> 4I(15 & frasl;2) transition. Judd-Ofelt analysis yielded intensity parameters following the trend Omega(2) > Omega(6) > Omega(4), indicating a moderately asymmetric environment and rigid glass network. The 1.5 mol% Er2O3-doped sample demonstrated a high stimulated emission cross-section (33.68 & times; 10(-22) cm(2)), a branching ratio greater than 0.5, and a broad emission bandwidth around 1.53 mu m. These characteristics suggest suitability for optical amplification. McCumber analysis revealed positive gain for population inversion levels exceeding 60%, supporting the material's potential for C-band optical communication. Overall, the investigated glass system is a promising candidate for use in near-infrared "eye-safe" lasers and optical amplifiers operating at 1.53 mu m.

Solar-pumped laser (SPL) is an alternative way to enhance solar energy harvesting, where the sunlight is directly converted to the laser beam and then specifically targeted to irradiate a solar cell device. As an essential part of the SPL system, a glass-based optical gain medium is required to create amplified emission light. In the present work, we reported glass fabrication using a melt and quenching technique with a composition of (40-x) TeO2 + 39 B2O3 + 10 CaO + 10 Al2O3 + 1 Dy2O3 + x Eu2O3 so-called xEu/Dy glass, where x = 0.0, 0.1, 0.3, 0.5, 1.0, and 3.0 mol%. From the absorption spectra, we find that xEu/Dy glasses have various wavelength from ultraviolet to infrared that is comparable with solar spectra. Meanwhile, the emission spectra of glass show several peaks in the visible region including 480, 579, 590, 614, 652, and 699 nm belonging to Eu3+ and Dy3+ emission bands under )lex = 395 nm. These emission lines are found similar to emission spectra under Dy3+ ion excitation )lex = 388 nm as well as the X-ray induced luminescence spectra. The CIE 1931 color coordinate is found to shift from yellow to the reddish-orange region along with their CCT coordinate under different excitation wavelengths. Our investigation shows that the emission spectrum of 3.0Eu/Dy glass overlapped with the absorption band of dye, organic, and perovskite photosensitizers. Our results demonstrate the feasibility of present glass for optical gain medium in SPL particularly to be integrated with third-generation solar cells.

Analysis and review of physical, structural, optical, and luminescence properties of dysprosium-doped zinc barium niobium boro-tellurite glass has been carried out. All glass samples were prepared by melting around 1.5 h at 1,150°C and annealing around 3 h at 350°C. Six different concentrations of Dy2O3 were used to prepare the glasses, ranging from 0.00 to 1.50 mol%. The samples were prepared, involving both shaping and refining, for density, refractive index, and optical/photoluminescence measurements at room temperature. Structural measurements were obtained using XRD, FTIR, and Raman spectroscopy. The absorption spectra demonstrate that the transition state of Dy3+ ion from 6H15/2 (ground state) to several excited states (6P7/2), (4F7/2+4I13/2), (6F3/2), (6F5/2), (6F7/2), (6H7/2+6F9/2), (6H9/2+6F11/2), and (6H11/2) at wavelengths of 350, 394, 759, 804, 903, 1,094, 1,276 and 1,681 nm, respectively. The sample was excited with a xenon flashlamp of 453 nm, which produces 3 emission peaks at 482, 574, and 661 nm associated with the transitions 4F9/2→6H(11/2, 13/2, and 15/2), in that order. The combination of blue light from energy level 4F9/2→6H15/2 and yellow light from energy level 4F9/2→6H13/2 resulted in white light emission, as corroborated by the CIE 1931 chromaticity diagram. The Lifetime exhibits a diminishing trend as the concentration of Dy2O3 increases. According to the Judd Ofelt (JO) intensity values, the trend was Ω2 > Ω4 > Ω6 observed. The radiative parameters utilized to assess the suitability of these glasses for laser operation in the visible range were the branching ratios (βR), transition probabilities (AR), and stimulated emission cross-sections (σe) for the 4F9/2→6H13/2 transition. The current Dy3+ ion doped zinc barium niobium borotellurite glasses are thus suggested to be ideal for applications of white light and optical devices.
