Summary: This study reports the incorporation of Sm3+ ions into the crystalline phase of Sm2Si2O7 in an aluminoborosilicate glass matrix through melting quenching and heat treatment processes. The obtained glass ceramics were characterized using X-ray diffraction, Fourier transform infrared spectroscopy, and field emission scanning electron microscopy. Absorption studies indicated improved crystallinity in the glass network, resulting in low bandgap values and high Urbach energy values. Excitation and emission studies showed enhanced intensities compared to the unheated base glass. The glass ceramics exhibited longer lifetimes of Sm3+ ions in the 4G5/2 level and emitted reddish-orange light. Therefore, Sm3+ doped Sm2Si2O7 glass ceramics are promising materials for solid-state lighting and laser applications.

Summary: Transparent glass ceramics containing Ba3Gd2F12:Yb3+/Er3+ nanocrystals were successfully prepared using the traditional melt quenching method, with their structure and upconverted luminescent properties studied in detail. These glass ceramics exhibited longer lifetime and higher emission intensity compared to precursor glass. Additionally, the temperature dependence of fluorescence intensity ratio was investigated, showing maximum relative sensitivity at 296 K. These results suggest that the GCs embedded with Ba3Gd2F12:Yb3+/Er3+ nanocrystals could be a promising candidate for optical temperature sensors.

Summary: Eu3+ doped and Er3+/Yb3+ codoped glass ceramics with NaLa(WO4)2 nanoparticles were prepared and their optical and temperature sensing properties were investigated. Eu3+ ions showed enhanced photoluminescence intensity due to selective entering into the precipitated NaLa(WO4)2 nanoparticles, while Er3+/Yb3+ ions showed improved visible upconversion emissions and near-infrared photoluminescence due to enrichment in low phonon-energy NaLa(WO4)2 nanoparticles. The temperature sensitivity of 0.014K-1 at 476K demonstrates the potential of Er3+/Yb3+ codoped NaLa(WO4)2:glass ceramics for optical temperature-sensing applications.

Summary: In this study, transparent glass-ceramic composites embedded with Ln-fluoride nanocrystals were prepared to enhance the upconversion luminescence of Tm3+. By inducing Yb3+, KYb3F10 and KYb2F7 nanocrystals were controllably precipitated in the glass ceramics, resulting in enhanced emission intensities due to the effective incorporation and substitution of Tm3+ into the crystal structures. This controllable nano-crystallization strategy opens up a new pathway for engineering a wide range of functional nanomaterials with Ln(3+) ions effectively incorporated into fluoride crystal structures.

Summary: Thin film polyethylene oxide, produced by the thermal evaporation technique, exhibits structural and property differences compared to bulk polyethylene oxide. The dielectric constant of polyethylene oxide thin film is 10 times greater than that of bulk polyethylene oxide. There is consistency among dielectric constants, activation energies, and free volume fractions for both thin film and bulk samples. Polyethylene oxide thin film is observed to be more brittle than bulk polyethylene oxide.

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.

Summary: The relationship between the heterogeneous structure and structural relaxation in metallic glasses was explored by investigating the quasielastic and viscoelastic behavior of a Zr55Cu30Ni5Al10 metallic glass. Stress-annealing treatment was used to retain elastic strain energy, and a unique creep recovery phenomenon was observed during the reheating process. The Maxwell model was employed to qualitatively describe the mechanisms of elastic strain energy retention and release.
