Ultra-broad-band white emitting phosphors have a wide application prospect in the new generation of illumination systems. Due to the sensitivity of Bi3+ to the surrounding environment, it exhibits different luminescence properties in different crystallographic sites, which makes it easy to achieve white emission. Cationic substitution engineering is the most effective strategy for controlling the environment around Bi-site and realizing the spectrum tuning. Herein, we conducted substitution engineering in K2MgGeO4:Bi3+ (KMGO:Bi3+) that uses alk...
