It was indicated by SEM spectra of ZnO thin films that the surface of the sample was leveled off, and the crystals were felsitic. It was found from the experiment that, with the increasing of substrate temperature, there were more oxygen vacancies in the films, which lead the conductance of the sample become larger , and the absorb edge of ZnO thin films shifted toward higher wavelength; with increasing of Ar:O2 ratio, there were lesser oxygen vacancies in the films, which lead the absorb edge of ZnO thin films shifted toward lower wavelength.

实验还发现，随着衬底温度的升高，薄膜中产生的氧空位将会增多，使得ZnO薄膜的电导逐渐增大，而且其紫外透射吸收截止边带向高波长方向漂移；随着氩氧比例的增加，薄膜中的氧缺陷相对减少，薄膜的透射吸收截止边向低波长方向漂移。
