Abstract:Near-infrared (NIR) phosphors are enablers for NIR phosphor-converted light-emitting diodes (pc-LEDs). However, fewer NIR-emitting phosphors with both high internal/external quantum efficiency (IQE/EQE) and thermal stability are discovered, which obstructs the promotion of NIR pc-LEDs. Herein, by partially replacing Al3+ in K-β-Al2O3:2Cr3+ with Ga3+, the photoluminescence (PL) intensity of the sol
