Summary: Optical spectroscopy and defect disorder of Eu-doped NaYF4 and NaY(1-x)GdxF(4) structures were studied through computational and experimental methods. Atomistic modeling was used to predict intrinsic disorder and Eu doping sites, and calculate crystal field parameters. The experimental emission spectrum of Eu-doped structures was obtained, showing agreement with theoretical predictions of local symmetry.

Summary: Metastable and transient photoinduced phenomena in as-deposited amorphous AsxS100-x films were investigated using a waveguide technique. The dynamics of the sub-bandgap mode absorption and the irreversible changes and transient variation of the film refractive index were studied. The findings suggest that these phenomena are influenced by two competing processes and are primarily caused by changes in interatomic bond strength and polarizability near sulphur atoms.

Summary: Atomistic simulation was used to study the defect process caused by europium in the NaCdPO4 structure. The calculations showed that the most favorable intrinsic defect type is cation anti-site defect, and doping by Eu3+ on the Cd site is energetically favorable. Charge compensation by Na-Cd anti-site defect is also probable. Crystal field parameters were calculated to discuss the local symmetry of Eu3+.

Summary: Little is known about the mechanisms behind the induction of gyrotropy and macroscopic deformations in amorphous As2S3 when illuminated by linearly polarized continuous-wave laser light. It is believed to involve scattering and deflection of the incident light, negative photoinduced birefringence, and atomic motions triggered by photoinduced fluidity.

Summary: ZnO nano- and microstructures doped with K were successfully grown by the Vapor-Solid method. The morphology of the structures varied, including wires, needles, ribbons, triangular plates, and ball-shaped structures. The different lattice positions occupied by K ions depending on its concentration in the structures result in variations in morphology, crystalline quality, and luminescence emissions. The elongated structures were found to have the potential to act as waveguides and optical resonators.

Summary: In this study, improved resolution of bright afterglow emission was achieved by performing photoinduced triplet depletion. Triplet depletion was achieved by charge separation through photoionization from a triplet state caused by depletion and subsequent rapid singlet formation. A higher-resolution afterglow image with an improvement of 25% was obtained by simultaneous focusing of a donut-shaped depletion beam and an excitation beam.

Summary: This study demonstrates a photoinduced single-crystal to single-crystal transformation through conformational change. By UV light induction, a conformational change in 3-methylene-2-(quinolin-8-yl) isoindolin-1-one (MQIO) derivatives leads to the SCSC transformation from monoclinic to triclinic phase. The transformation is accompanied by turn-on fluorescence and shape changes of the single crystal.

The optical parameters and structural parameters of the solid solutions were analyzed, and it was found that increasing the Ge content can decrease the pseudo-gap energy and Urbach energy of the materials. This suggests that the single crystalline Ag7+x(P1-xGex)S-6 has potential applications in solar harvesting.

Summary: In this paper, the laser characterization of Cr:ZnS/Se polycrystalline gain media in different cavities is demonstrated. The spectral output of lasers based on these gain elements in non-selective unpolarized and linearly polarized cavities was measured to be broadened due to the spatial hole burning effect. However, SHB alleviation and linewidth narrowing were achieved in the twisted mode cavity by adjusting the orientation of intracavity waveplates.

Summary: A dissimilarity measure of local structure using the Wasserstein distance is proposed to efficiently search for novel phosphors. This method provides quantitative explanations for the dissimilarity of local structures and can identify candidates for novel narrow-band phosphors based on correlations with the full width at half maximum. The approach is useful for the search of novel phosphors and expected to be applied in materials searches in other fields where local structures are important.

This study found that about half of Eu ions in the YSiO2N host were reduced to the divalent state during the sintering process, without any annealing processes. The prepared Eu2+/3+-doped YSiO2N sample showed anomalous deep-red to near-infrared luminescence under violet light illumination, and detailed spectroscopic analyses were conducted to understand its luminescent properties.

Summary: In pursuit of new mechanically responsive luminescent materials, the study aims to differentiate triboluminescence (TL) from photoluminescence (PL). A beta-diketonate ligand with tert-butyl groups is used to quench Eu-III-centered PL and provide efficient photosensitization of Tb-III ions. Nanomechanical tests reveal the ductility of the crystals, making them ideal for accumulating deformation energy before breakage. Additionally, the study investigates the TL/PL color difference and mechanochromic luminescence (MCL) in a Tb-III/Eu-III heterodinuclear complex.

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.
