Summary: A novel K3(Y0.88Yb0.10Er0.02)Si2O7 phosphor was synthesized and investigated for its up-conversion luminescence and optical thermometric performance. The phosphor exhibited strong green UC emission and could sense temperature through fluorescence intensity ratio (FIR) and fluorescence lifetime (FL) modes. The maximum absolute sensitivity (SA) and relative sensitivity (SR) were higher than previous studies, with SA = 156 x 10-4 K-1 (I531/I555, 298 K) and SR = 1.80% K-1 (I519/I555, 298 K) via the FIR mode, and SA = 661 x 10-4 K-1 (548 K) and SR = 9.77% K-1 (298 K) via the FL mode.

Summary: Lithium-boron-aluminum glasses doped with Eu3+ were prepared and heat treated to produce glass ceramics. X-ray diffraction measurements confirmed the formation of crystalline phases, and an increase in emission intensity was observed after the heat treatment. The luminescence analysis indicated the presence of Eu3+ in low-symmetry sites, and the intensity parameters remained unchanged after the heat treatment. The materials showed promising potential as optical temperature sensors with a high relative sensitivity.

Summary: To develop new inorganic multifunctional materials, Yb3+/Er3+ doped precursor glasses (PGs) were fabricated and a niobate transparent photoelectric glass ceramic (GC) was gained via controlled crystallization of PG. The up-conversion (UC) luminescence performance in GC was significantly increased compared to PG. The dual-mode optical temperature measurement was realized through fluorescence intensity ratio (FIR) methods, with an ultimate absolute sensitivity (Sa-max) of 0.68 %K-1 and relative sensitivity (Sr-max) of 0.85% K-1 based on thermal/non-thermal coupling energy levels (TCELs/NTCELs). The single-layer capacitor made of GC exhibited an energy density of 0.83 J/cm3 (@600 kV/cm) and a power density of 210 MW/cm3. This work suggests potential applications of niobate transparent glass ceramics in optical thermometry and pulse energy storage.

Summary: This study investigates the influence of photocarrier transmission on the energy transfer of trivalent rare earth-doped inorganic crystals. The researchers discovered that efficient separation of photocarriers can inhibit the energy transfer between Er3+ and Yb3+ ions, thereby suppressing infrared emission. Additionally, the separated photoholes block the recombination of excited electrons, preventing further energy transfer.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
