Abstract

Sr₂SiO₄:Eu²⁺ and Sr₂SiO₄:Eu²⁺,Dy³⁺ phosphors were prepared by solid state reaction in reducing atmosphere. Photoluminescence (PL), photostimulated luminescence (PSL) after ultraviolet irradiation of the phosphors were investigated. Broad blue light emission centered at 470nm and green light emission centered at 535nm , under the excitation of 320nm and 365nm, were observed in all these phosphors. Comparing with Sr₂SiO₄:Eu²⁺,the PL intensity of doubly doped Sr₂SiO₄:Eu²⁺,Dy³⁺ was found to decrease. Under 980nm infrared stimulation, prominent PSL was observed in Sr₂SiO₄:Eu²⁺,Dy³⁺ after 254nm ultraviolet irradiation. The results indicate that Sr₂SiO₄:Eu²⁺,Dy³⁺ has potential as a promising optical storage material.
