Summary: This study successfully prepared phosphor samples based on Ca3-xLuxSc2-xMgxSi3O12:Ce3+ and investigated their luminescence properties. With the increase in Lu-Mg concentration, the peak of the sample redshifted, but the thermal stability gradually decreased. The LD devices made from CLSMS:Ce3+ fluorescent materials showed a decrease in cyan-green light and an increase in red light as the Lu-Mg concentration increased.

Summary: In this study, Eu3+ single-doped Ca2Sb2O7:Eu3+ phosphors with high relative sensitivity (Sr) were developed for dual-emitting-center luminescence thermometry. The anti-thermal quenching behavior of Eu3+ originating from the energy transfer (ET) of host->Eu3+ was found and proved. Adjustable color emission from blue to orange was achieved. The developed phosphors are expected to be prospective candidates in luminescence thermometers and LED devices in various conditions due to their excellent performance in optical thermometry, color-tunable properties, and outstanding acid and alkali resistance for PDMS films.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
