| Abstract: | A new synthesis method of SrAl 2O 4: Eu 2+ , Dy 3+ Phosphorescent Material is introduced in this paper. The precursor of this phosphor was prepared by hydrothermal method firstly; then it was sintering under high temperature and reductive air. The excitation spectrum, emission spectrum and long afterglow phosphorescent property have been measured. The long afterglow property of SrAl 20 4: Eu 2+ , Dy 3+ Phosphorescent Material prepared by hydrothermal method and complex-precipitation method were also compared in this paper. |
