摘　　要：采用溶胶-凝胶法在玻璃表面制备了TiO_2薄膜、ZnFe_2O_4薄膜和掺杂ZnFe_2O_4的TiO_2薄膜。利用紫外吸收光谱测定了薄膜的激发波长,计算得到了禁带宽度,并通过光催化分解实验进行了验证。Three kinds of films were prepared on glass substrate with the sol-gel method, including TiO2 films, ZnFe2O4 films and TiO2 films doped with ZnFe2O4. The extreme wave-lengths were measured by ultraviolet spectrum,then energy-gaps were calculated and verified through photocatalytic degeneration experiment.
