Abstract: This paper investigates reaction mechanism and electrochemical behavior of ZnO thin films deposited on transparent conducting glass from a simple aqueous zinc nitrate solution. Nanocrystalline ZnO films with grain sizes of 10~15 nm are obtained by controlling the growth rate of ZnO. XRD analysis demonstrates that the nanocrystalline ZnO thin film has phase purity and wurtzite structure. Optical characterizations show that such film has high optical transmittance (up to 90%) in the visible wavelength range and its band gap is 3.37 eV.
