A high quenching content red-emitting phosphor based on double perovskite host BaLaMgSbO6 for white LEDs

BaLa1-xEuxMgSbO6 can obtain strong red-emitting based the delayed concentration quenching of double perovskite host BaLaMgSbO6. The coordinates gradually shifted close to the standard red light (0.67, 0.33) with an increasing R/O value.319
