摘　　要：采用溶胶-凝胶和水热法制备了Ca_(0.9)MoO_4:Eu_(0.05)^(3+)M_(0.05)^+(M=Li^+,Na^+,K^+)红色荧光粉,探究了不同制备方法对样品发光性能的影响。利用荧光分光光度计对所合成样品的发光性能进行表征,研究了不同制备条件对Ca_(0.95)MoO_4:Eu_(0.05)^(3+)(M=Li^+,Na^+,K^+)荧光粉发光性能的影响。结果显示,溶胶-凝胶法制备的Ca_(0.9)MoO_4:Eu_(0.05)^(3+)Li_(0.05)^+荧光粉样品发光强度较好。Ca0.9MoO4：Eu0.05^3＋ Mo.05^＋ （M=L1^＋ ,Na^＋ ,K^＋ ） red phosphors were respectively prepared by sol-gel and hydrothermal method. The effect of different preparation methods on the luminescent properties of the samples was studied, and the effect of different preparation conditions on the luminescent properties of Cao.95MoO4： Eu0.05^3＋（M=Li^＋,Na^＋,K^＋） phosphors was investigated by fluorescence spectrophotometer. The results show that the luminescence intensity of Cao.9MoO4：Eu0.05^3＋Li0.05^＋ phosphor prepared by sol-gel method is better.
