摘要：

Green phosphor is an essential component in phosphor-converted white light-emitting diodes (pc-LEDs). Herein, a novel green-emitting phosphate phosphor Sr8ZnY(PO4)7:Eu2+ (SZYP:Eu2+) was synthesized through hydrothermal reaction method. The crystal structure, photoluminescence properties as well as thermal stability of SZYP:Eu2+ were investigated systematically. SZYP:Eu2+ can be efficiently excited by n-UV light in the range from 220 to 550 nm and shows a broad emission band centered at 520 nm with a full width at half maximum of 86 nm. The opti...
