研究了溶胶-凝胶法制备的金红石型和金红石型二氧化钛薄膜的光电化学性能。通过改变还原气氛、温度和时间等条件，研究了氧缺陷对光电化学性能的影响。结果表明：氧缺陷对光电流特性起关键作用;氧缺陷对电致发光特性有显著影响;红外波段的电致发光强度Γ x（峰值位于840 nm）反映了光电流的降低程度
Photoelectrochemical properties of titanium dioxide films in the anatase and rutile form which were prepared by the sol-gel method were investigated. The effects of oxygen defects on photoelectrochemical properties were investigated by varying the reduction conditions such as atmosphere, temperature, and time. It is shown that (i) oxygen defects play a key role in photocurrent characteristics, (ii) oxygen defects drastically affect electroluminescence characteristics, and (iii) the electroluminescence intensity Γ x , infrared band, which peaked at 840 nm, is indicative of the degree of the reduction
