The annealing treatment of ZnO thin film at various temperatures was performed. The effect of this treatment on the optical properties of ZnO thin film were investigated in order to apply this film to optoelectronic devices. The optical transmittance spectra were measured and it was found that the transmittance in UV-VIS region decreased with annealing temperature. The loss of light is mainly due to the increase of the carrier density, resulting from the increased oxygen vacancies during the annealing process at 300 degrees Celsius. It was also found that the absorption edge shifted to lower energy when the film was annealed at 300 degrees Celsius in air.
