摘　　要：文章主要研究了Y_(2)SiO_(5):Pr^(3+)上转换纳米荧光粉对ZnO:Pr^(3+)的光催化性能的影响,通过XRD、FE-SEM、FL和UV-Vis对样品的物相、形貌、发光性能和光催化行性能进行了分析表征,实验结果表明:随着Y_(2)SiO_(5):Pr^(3+)上转换纳米荧光粉的加入量增加,ZnO:Pr^(3+)光催化效率逐渐提高,当加入0.2 g Y_(2)SiO_(5):Pr^(3+)时,光催化效率最高,在光照60 min后对亚甲基蓝的降解率达到了98.11%,相比未加入Y_(2)SiO_(5):Pr^(3+)时的光催化效率有显著提升。In this paper,the effect of Y_(2)SiO_(5):Pr^(3+)up-conversion nano-phosphors on the photocatalytic properties of ZnO:Pr^(3+)was studied,and the phase,morphology luminescence properties and photocatalytic properties of the prepared samples were characterized by the XRD,FE-SEM,FL and UV-Vis.The result showed that the photocatalytic efficiency of ZnO:Pr^(3+)gradually increased with the increase of the amount of Y_(2)SiO_(5):Pr^(3+)up-conversion nano-phosphors.When the amount of Y_(2)SiO_(5):Pr^(3+)was 0.2 g,the photocatalytic efficiency of ZnO:Pr^(3+)was the highest,and the degradation rate of methylene blue was 98.11%after 60min of illumination.The photocatalytic efficiency of ZnO:Pr3+was significantly improved compared with that without Y_(2)SiO_(5):Pr^(3+).
