摘　　要：采用微波水热法合成了YBO3∶Pr^3+上转换发光材料,通过X射线衍射、冷场发射扫描电镜和荧光光谱对样品的物相、形貌和发光性能进行了分析表征。结果表明:所得YBO3∶Pr^3+样品为六方晶型,具有纳米片组成的球形花簇状结构,可将450~525nm的可见光转换成250~350nm的近紫外光;YBO3∶Pr^3+的最佳合成温度为200℃,Pr^3+的最佳掺杂量为x=0.010mol;Y0.99BO3∶0.01Pr^3+与ZnO复合能明显地提高ZnO的光催化效率,ZnO/Y0.99BO3∶0.01Pr^3+复合光催化剂在光照120min后降解效率达到了98%。YBO3∶Pr^3+up-conversion luminescence materials were synthesized by microwave hydrothermal method,and the phase,morphology and luminescence performance were characterized by the XRD,FE-SEM,and FL.The results showed that the synthesized YBO3∶Pr^3+sample had hexagonal phase with spherical flower cluster structure composed of sheet nanocrystals,which converted visible light of 450~525nm into near-ultraviolet light of 250~350nm.The best synthesis temperature was 200℃,and the best doping amount of Pr^3+was 0.010mol.The photocatalytic properties of ZnO were improved significantly by recombining with Y0.99BO3∶0.01Pr^3+,the degradation efficiency of ZnO/Y0.99BO3∶0.01Pr^3+composite photocatalyst reached 98%after 120min of illumination.
