Abstract

In the present paper, we report the optical properties of the bicolor composite phosphor on the base of CaS and Ga~2~S~3~ and study the possibility using this composite to obtain a white light LED. In particular, the energy transfer between the green and red emission bands of the bicolor composite phosphor activated by Eu^2+^ ions was studied. (Β© 2009 WILEY‐VCH Verlag GmbH & Co.

The Eu 2+ -and Ce 3+ -doped CaAl 2 S 4 phosphors were comparatively synthesized by conventional solid-state reaction and the evacuated sealed quartz ampoule. The X-ray diffraction (XRD) patterns show that the sample with better crystalline quality was prepared by the evacuated sealed quartz ampoule,
