Eu2+ doped aluminosilicate phosphors (Ca2AlMg0.5Si1.5O7:Eu2+ (CAMS:Eu2+)) for white near-UV w-LEDs have been synthesized by solid-state reaction at 1250°C. The phase and crystal structure of CAMS have been analyzed by using XRD. The material with a relatively low Eu2+ concentration displayed a peak in excitation spectrum at 372nm and a tunable emission spectrum. The colorimetric coordinate of sample...
