Summary: In this study, the emission properties of MgAl2O4 wafers with different crystal orientations were investigated using hard X-ray-excited optical luminescence (XEOL). MgAl2O4(110) exhibited the lowest XEOL emission intensity due to its thermochemical instability and poor ability to generate oxygen vacancies. By analyzing the XEOL spectra, clear emission peaks corresponding to color centers in MgAl2O4 wafers and the radiative transition of Cr ion impurities were identified. Furthermore, the combination of XEOL, X-ray fluorescence spectroscopy (XRF), and X-ray absorption spectroscopy (XAS) was demonstrated to effectively analyze elemental distributions and valence states in the samples.

Summary: By studying the effect of different Yb3+ concentrations on Er3+ and Yb3+ co-doped phosphors, it was found that increasing the concentration of Yb3+ decreases the visible emission intensity of Er3+ but increases the near-infrared emission of Yb3+. Furthermore, Yb3+ can enhance the up-conversion luminescence of Er3+. The results suggest that the energy transfer between Yb3+ and Er3+ ions is reversible.

Summary: This study successfully developed a type of phosphor doped with Eu2+ and Er3+ ions, which exhibits four anti-counterfeiting modes including photo, long persistent, photo-stimulated, and upconversion luminescence. The phosphor emits intense blue-green luminescence and rapidly changes to stable green luminescence with the delay of excitation time.

Summary: This study demonstrates a design approach for wavelength-specific light dosimeters based on photo-induced redox processes of certain lanthanides in phosphate compounds, enabling selective monitoring of UV and visible light doses. The reduction process is induced through ligand-to-metal charge transfer excitation, while the oxidation process is achieved through excitation of the involved hole traps or 4f(N)-4f(N-1)5d(1) transitions of the created divalent dopants. The dose and wavelength-dependent redox processes allow for tailored spectral sensitivity of the dosimeter, making it suitable for personal solar UV radiation monitoring.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
