| Abstract: | The rare earth ion has been widely applied to as an activator in luminescent materials. This paper reported the luminescent mechanisms of Eu with different valence states. All factors which effect on the valence state stability of Eu were also offered. The effects of assistant activator of rare earth with trivalent state on the afterglow of phosphor were summarized. |
