Abstract

Novel orange-red emitting phosphors, Ba2Zn1-xWO6:xSm3+(x?=?0.03, 0.04, 0.05, 0.06 and 0.07) (BZW:Sm3+), were prepared using a high-temperature solid-state reaction method. Their crystal structure and photoluminescence properties were characterized and the mechanism of energy transfers between Ba2ZnWO6and Sm3+elucidated in detail. It was found that the phosphors had a cubic structure with space groupFm3ˉm. They can be excited by near-ultraviolet light, and the characteristic emissions of Sm3+ ions are observed at 564?nm, 598?nm and 645?nm, corresponding to4G5/2?→?6H5/2,4G5/2?→?6H7/2and4G5/2?→?6H9/2transitions, respectively. The4G5/2?→?6H
