摘要
采用溶胶-凝胶法在普通的载玻片上制备了锐钛矿型TiO2和过渡金属Cu离子掺杂TiO2薄膜.通过XRD,UV-VIS,XPS,AFM表征了合成的薄膜,表明铜离子掺入后,薄膜变得更加致密.铜离子以Cu2O的形式存在.在紫外光照射下,TiO2薄膜表现出明显的亲水性.对于掺铜的TiO2薄膜,随着铜掺杂量的增加,铜（Ⅰ）对亲水性能的抑制作用亦增强.
Transparent TiO2 thin film and Cu-doped TiO2 thin film were prepared by the sol-gel method on the soda lime glass substrates. The change of hydrophilicity of the films under UV illumination was investigated. The results of XRD, UV-VIS, XPS and AFM show that Cu ions are in the form Of Cu2O. The addition of Cu ions can suppress the grain growth of crystals in the TiO2 thin film. Pure TiO2 thin film can be entirely wetted by water after UV illumination for 5h and shows good hydrophilicity. The hydrophilicity of TiO2 will decrease with increasing amount of Cu dopants.
