| 摘 要： | The sol-gel process is used in the preparation of nanostructure materials with Ti（OC4H9）4 as precursor in the start materials. TiO2 gelatin is obtained through hydrolysis and condensation process. Rare earth such as La2O3, CeO2, Eu2O3 and Gd2O3 are introduced into the nanostructure TiO2 to improve the anti-UV capacity. The phase structure of pure TiO2 and doped TiO2 and their anti- UV capacity are studied by means of XRD and UPF. The optimum doping and heat treatment temperature are chosen.

| Abstract: | The sol-gel process is used in the preparation of nanostructure materials with Ti(OC_ 4 H_ 9 )_ 4 as precursor in the start materials. TiO_ 2 gelatin is obtained through hydrolysis and condensation process. Rare earth such as La_ 2 O_ 3 , CeO_ 2 , Eu_ 2 O_ 3 and Gd_ 2 O_ 3 are introduced into the nanostructure TiO_ 2 to improve the anti-UV capacity. The phase structure of pure TiO_ 2 and doped TiO_ 2 and their anti-UV capacity are studied by means of XRD and UPF. The optimum doping and heat treatment temperature are chosen. |
