摘要 本文报道了利用 Ce O2 ,Tb4 O7和 Sr Al2 O4 为主原料合成 Sr Al2 O4 :(Ce,Tb)光致绿色发光粉体研究结果 ,实验研究表明 Ce3+ ,Tb3+ 含量、保温时间等主要合成条件对合成样品发光性能具有重要影响 。 Green photoluminescent powder of aluminate strontium (cerium,terbium) is prepared by utilizing ceria,terdia and aluminate strontium. The result of experiment reveals that luminescent performance of specimen is mainly affected by the contents of cerium and terbium, and by thermal insulation. The luminescent mechanism of Ce 3+ and Tb 3+ is discussed preliminarily.
