By using the spray pyrolysis method, zinc oxide(ZnO) was produced from zinc acetate, the surface morphology of the prepared films was investigated by using scanning electron microscopy. The thickness of ZnO thin film was increased up to 460℃ and it was 833 nm. The maximum wavelength of absorption was obtained at 365 nm, and the maximum peak of fluorescence at 475 nm and 505 nm. ZnO film have been characterized by XPS, XRD, and SEM. XRD results show that all the films are preferred orientation along the (002) plane which is depend on the substrate temperature. The optimal temperature to produce ZnO was determined at around 460℃ from measurements of XPS, XRD and photocurrent. It was also shown that the homogeneous particles had the higher photocurrent.
