Synthesis and Photoluminescence Properties of Sr₃SiO₅:Eu²⁺, Mn²⁺

Abstract:

The Mn2+ co-doped Sr₃SiO₅:Eu²⁺ phosphorsynthesized by conventional solid-state reaction had been investigated. Two controlling factors, firing temperature and Eu²⁺ concentrations, regarding to the synthesis and photoluminescence properties of Sr₃SiO₅:Eu²⁺ samples have been elucidated through photoluminescence (PL) analyses. The best firing temperature and Eu²⁺ concentrations of Sr_3-xSiO₅:Eu²⁺_x phosphor was shown to be 1600oC and 0.03mol, respectively. In addition, the Mn²⁺ co-doped into Sr₃SiO₅:Eu²⁺, i. e. Sr_3-x-ySiO₅:Mn_x²⁺,Eu_y²⁺, were also studied by PL analysis. It showed that the luminescent efficiency of Mn2+ co-doped into Sr3SiO5:Eu could be enhanced by 7%, as compared to the Sr₃SiO₅:Eu²⁺ phosphor. This study provides the fundamentals of synthesis and photoluminescence properties of (Sr_3-x-ySiO₅):Eu_x²⁺,Mn²⁺_y phosphor for future research and application.
