Summary: Changing the Ga:Al ratio modulates the energy gap and modifies the spectroscopic properties of the phosphors. The stabilization of the Gd3Ga5O12 garnet structure by Al3+ ions widens the energy gap. Increasing Ga content leads to a decrease in the energy gap, affecting the interaction between oxygen ligands and luminescent ions.

Summary: Introducing smaller Mg2+ ions to replace Ca2+ site in the BaLaCaSbO6 matrix leads to a significant enhancement in luminescence intensity, red-shift, and luminescence lifetime. These modulations are mainly attributed to the strengthen pressure on the local structure, superior lattice rigidity, and suppression of non-radiative transition after the substitution of smaller Mg2+. The effective lifetime-based luminescence thermometry is achieved due to thermal quenching behavior of Mn4+ ions in the matrix.

Summary: Narrower band red and green emission in phosphor-converted white light-emitting diodes can be achieved by using Mn2+ as a luminescent ion. The luminescence quenching temperature of Mn2+ is shown to vary greatly depending on the host material, with a positive correlation with the bandgap of the host. The quenching mechanism is found to be thermally activated photoionization, and a wide-bandgap host material is required for temperature-stable Mn2+ luminescence in high power LEDs.

Summary: Mobility spectrum analysis (MSA) is used to separate carrier density and mobility of majority and minority carriers in multicarrier semiconductors. In this study, p-GaAs layer is analyzed using MSA to demonstrate its application in defect analysis. Results show that the presence and peak position of defect state can be predicted by comparing the density ratio of minority and majority carriers. DLTS signals dominate around a specific temperature, consistent with the temperature-dependent generation-recombination and thermionic emission peaks.

Summary: Solar-driven CO2 conversion into chemical fuels using photocatalysts is a sustainable method for renewable energy. However, the low photocatalytic activity is limited by poor photoabsorption, low charge separation efficiency, and sluggish interfacial reaction. To address this issue, a mesh cladding structure of Sr-doped LaFeO3/Bi4O5Br2 photocatalyst with abundant surface oxygen vacancies (OVs) is developed. The optimized photocatalyst with appropriate Sr doping and BOB content shows a considerable methane generation, which is significantly higher than the pristine LFO.

Summary: The 20NaF-60P2O5-20Na2O fluorophosphate glass systems doped with 3 wt% of CoO and NiO were investigated for their optical parameters before and after gamma irradiation. The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
