Synthesis and Characterization of Nanosized Phpsphor SrS:Eu2+,Sm3+ by a Hydrothermal Process

Article Preview

Abstract:

Electron trapping materials SrS:Eu2+,Sm3+ were prepared by hydrothermal method at 200 °C for 5 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 sun light, It can be seen that the PSL emission spectra was a band spectrum with one peak at 605 nm, and this emission was ascribed to characteristic 5d → 4f transition of Eu2+, and the photo stimulated luminescence phenomenon was observed.
