Abstract
Electron trapping materials SrSO4:Eu2+ were prepared by hydrothermal method at 200 °C for 20 h. The phase structure, microstructure and optical properties were characterized by XRD, SEM, EDAX, PL, PSL and TL, respectively. The sample was stimulated by a 980 nm infrared laser after exposing to the UV light. It can be seen that the PSL emission spectra had two bands with peaks at 793 nm and 835 nm, and the photo stimulated luminescence phenomenon was observed.
