摘要：

The novel orange emitting long persistent phosphor (LPP) Sm3+-doped CdGeO3 was prepared successfully via a traditional high temperature solid-state reaction method. It shows orange long persistent luminescence (LPL) after the excitation by ultraviolet light. The optimal concentration of Sm3+ ions for the brightest photoluminescence (PL) emission and the best LPL characteristic were experimentally determined to be about 1 mol% and 0.5 mol%, respectively. The incorporation of Sm3+ ions into the CdGeO3 host has a great influence on the trap density. Furthermore, the origin and the mechanism of the orange LPL were also discussed.
