Summary: Ongoing efforts are being made to develop novel phosphors with natural-looking properties under sunlight. Rare-earth pyrosilicates, such as La2Si2O7 (LSO), are considered as promising scintillators and protective pigments due to their stability. This study successfully developed Eu3+-activated dumbbell-shaped LSO nanocrystalline phosphors, exhibiting strong red emission under UV excitation and chromaticity coordinates in the reddish-orange region.

Summary: Sr3Gd(PO4)(3) phosphors activated with different concentrations of Dy3+ ions were fabricated and their optical properties were investigated. Strong and efficient emission was achieved by optimizing the Dy3+ concentration. It was observed that energy transfer among the excited Dy3+ ions occurred through dipole-dipole interactions at higher concentrations.

Summary: In this study, BaGd2ZnO5:Sm3+ nanophosphors were successfully synthesized through urea-assisted combustion synthesis, exhibiting orthorhombic symmetry and cool white light luminance. The agglomerated particles had non-uniform shapes and sizes between 30 and 40 nm. The nanophosphors showed a fine peak at 601 nm in the PL emission spectra, indicating good luminescent properties. The exchange-type interrelations were found to be the primary mechanism for the non-radiative relaxing of energy in the nanophosphors.

Summary: A series of Pr3+ activated YAl3(BO3)(4) phosphors were successfully fabricated and characterized in terms of phase, morphology, and photoluminescence properties. The phosphors exhibited intense-yellow to pale-yellow tunable emission under visible wavelength excitation, attributed to dipole-dipole interaction energy-transfer among excited Pr3+ ions.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.

Summary: Drug-loaded cellulose diacetate (CDA) membranes were prepared using different compositions of mixed solvent. The microstructure and performance of the membranes were investigated, and a method to predict drug release properties was proposed. The results showed that the composition of the mixed solvent significantly affected the overall performance of CDA membranes, and the release rates of drugs were related to Δdelta and the intrinsic viscosity of CDA.
