Abstract

Tuning and optimizing luminescent properties of oxonitridosilicates phosphors are important for white light-emitting diode (WLED) applications. To improve the color rendering index, correlated color temperature and thermal stability of layer-structured M Si 2 O 2 N 2:Eu (M = Sr, Ba) phosphors, catio...
