摘　　要：采用水热法制备出Ca_3(PO_4)_2:Dy^(3+)纳米荧光粉,通过XRD、SEM和荧光光谱对样品进行了分析,主要研究了制备工艺以及Dy^(3+)离子掺杂浓度对材料发光性能的影响规律。研究结果表明:初始溶液pH值为7,反应釜填充度为80%,在180℃条件下反应24 h所得的Ca_3(PO_4)_2:0.02 Dy^(3+)纳米荧光粉发光性能最佳。SEM分析表明荧光粉颗粒的平均粒径为100 nm,分散性好。In this paper,Ca3（ PO4）2∶ Dy^3＋nano-phosphors were prepared by hydrothermal method. The effects of Dy3＋concentration and preparation process on the luminescence properties of Ca3（ PO4）2∶ 0. 02 Dy^3＋nano-phosphor were studied by XRD,SEM,Photoluminescence（ PL） spectra and so on. The results indicate Ca3（ PO4）2∶ 0. 02 Dy^3＋nano-phosphor,filling 80 percent of reactor,with a pH value of 7 synthesizesd under condition at 180 ℃ for 24 h show the better luminescence intensity. In addition,SEM images show that particle size of phosphor is about 100 nm with good dispersion.
