Single Crystal Cr3+-Doped NIR Phosphor: Enhanced Luminescence Intensity and Improved Thermal Stability Single crystals of Cr³⁺-doped guanidine-based organic-inorganic hybrid fluorides (GA3GaF6:Cr3+) with sizes up to 6×5×2 mm3 were successfully synthesized using a facile room-temperature solvent exchange crystallization method. The GA3GaF6:Cr3+ single crystal exhibits near-infrared (NIR) emission centered at 802 nm with a full width at half-maximum (FWHM) of 130 nm upon blue light excitation.

Novel Mn4+-activated Fluoride Red Phosphor Cs30(Nb2O2F9)9(OH)3·H2O:Mn4+ With Good Waterproof Stability for WLEDs Red-light emitting materials, as one of the pivotal components for warm white light emitting diodes (WLEDs), have drawn increasing public focus. Among which, Mn4+ doped red-light emitting fluorides have drawn considerable attention in cooperation with InGaN chip, while they suffer poor water stability under humid conditions.

Banks operate internationally through networks of branches and subsidiaries, also known as foreign banking offices (FBOs). Newly collected system- and entity-level data across two dozen host countries confirm stylised facts on these entities' balance sheets and establish new ones.
