Study on the Luminescent Properties of Gd2-xEuxWO6 Red- emitting Phosphors Synthesized by the Sol- gel Method

利用溶胶-凝胶法制备系列Gd2-xEuxWO6红色荧光粉,XRD测试表明Gd2-xEuxWO6具有单斜晶系结构；在298 nm或395 nm激发下,荧光粉主要发射出对应于Eu3+5的D0→7 F2能级跃迁的612 nm红光；当Gd2-xEuxWO6中Eu3+的掺杂量为50％时,荧光粉612nm红光强度最强；在合成过程中适当添加聚乙二醇(PEG)和柠檬酸能改善荧光粉的红光发射强度.
