摘　　要：采用溶胶-凝胶法在发光材料(CaAl2O4:Eu2+,Dy3+)表面包覆了TiO2膜。研究了包覆颗粒的形貌、结构和发光性能。对包覆颗粒进行了光催化实验,并对其发光机理做了初步的探讨。Photogenic material(CaAl2O4:Eu2+,Dy3+) was coated with TiO2 film by way of sol-gel process. Morphology,structure and photocatalytic properties of the coated particles were investigated. Photocatalytic tests were carried out on thecoated particles and initial exploration was made of its photogenic mechanism.
