以碳酸钙、氧化锌、二氧化钛为主要原料，以氧化镨为激活剂，以氧化铕为辅助激活剂，以碳酸钠为电荷补偿剂，以硼酸为助熔剂，采用高温固相法对红色CaTiO3：Pr3+蓄光材料进行了试制研究。试制得到荧光余辉时间达20 min左右、发光效果良好的CaTiO3：Pr3+系红色荧光材料。对合成的荧光粉末进行了XRD、激发光谱分析检测，表明合成所得荧光粉的主晶相为CaTiO3。试验结果表明，在配料组成确定后，合成温度和保温时间对发光效果的影响较大。当合成温度为1100℃，保温时间为2h制备得到的荧光材料发光效果良好。

A series of tests were developed around CaTiO3:Pr3+red lfuorescent material. In this study, CaTiO3:Pr3+red persistent phosphors with good glowing effect and about 20 minutes’ decay time were prepared by high-temperature solid-phase method with CaCO3, ZnO, TiO2 as main raw materials, Pr2O3 as the activate agent, Eu2O3 as auxiliary activators, Na2CO3 as compensate for the charge, as lfux.Samples were characterized by means of powder X-ray diffraction (XRD) and laser spectral analysis. Result showed that main phase of the synthesized lfuorescent powder was CaTiO3:Pr3+. Results shown that glowing effect were signiifcantly inlfuenced by synthesis temperature and the soaking time, when composition determined, Optimum synthetic temperature was 1100℃, and soaking time was 2 hours..
