摘　　要：采用固相法制备Sr1.8Eu0.8-xBixV1.2P0.8O8(0≤x≤0.7)系列粉末样品.研究样品中的Bi和Eu的相互作用,并讨论相关机理.用X射线衍射和荧光分光光度计对样品的结构和光学性质进行研究,结果表明:x=0.30时,样品的发光强度最强.Sr1.8Eu0.8-xV1.2P0.8O8 （0 ≤ x ≤ 0.7 ） phosphors had been synthesized by the conventional solid-state reaction .We investigated the interaction between Bi and Eu in the samples ,and the related mechanism was discussed .The crystal structure and luminescence properties were investigated by means of XRD and fluorescence spectrophotometer . The results indicated that the strongest emission intensity was achieved for x=0.30 .
