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 Sr3-xSiO5:Eu2+x phosphor was shown to be 1600oC and 0.03mol, respectively. In addition, the Mn2+ co-doped into Sr3SiO5:Eu2+, i. e. Sr3-x-ySiO5:Mnx2+,Euy2+, 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 (Sr3-x-ySiO5):Eux2+,Mn2+y phosphor for future research and application. |
