Nitrides and oxynitrides isostructural to α-Si3N4 (M-α-SiAlON, M = Sr, Ca, Li) possess superb thermally stable photoluminescence (PL) properties, making them reliable phosphors for high-power solid-state lighting. However, the synthesis of phase-pu

Rare-earth-activated phosphors play key roles in controlling the optical quality of phosphor-converted white light-emitting diodes (pc-wLEDs), but it is still a challenge to discover new phosphors with interesting properties or structures. In this wo
