摘要：

Sr1.994-xSiO4:0.006Eu2+, xDy3+(x=0.001-0.006) phosphors were prepared by high-temperature solid-state reaction in a reducing atmosphere. The crystal structure and photoluminescence(PL) properties of Sr1.994-xSiO4:0.006Eu2+, xDy3+ phosphors were investigated with X-ray diffractomer(XRD) and spectrophotometer. The PL spectra and photostimulated luminescence(PSL) spectra show that all the luminescence centers are derived from Eu2+ ions. Under the excitation of 320 nm and 365 nm, blue light emission centered at 470 nm and green light emission centered at 530 nm can be observed. The thermoluminescence test proved that the trap of Sr1.994-xSiO4:0.006Eu2+, xDy3+ material is deep, and it is less affected by thermal disturbance at room temperature. Under the excitation of 800 nm infrared light, the trapped electrons are released and interact with holes in the luminescent center. After irradiated by 254 nm UV for 0.5 h, and stimulated with a 980 nm infrared laser, the phosphors exhibit obvious green PSL. The results show that Sr1.994-x-SiO4:0.006Eu2+, xDy3+ has optical storage characteristics. © 2021, Science Press. All right reserved.
