Abstract
Highly transparent ZnO thin films were made by electrostatic spray deposition for 60 minutes-120 minutes at 400 degrees C on soda-lime-silica slide glass substrates. The peaks in the X-ray diffraction analysis could be indexed as from the structure of crystalline zinc oxide. From surface observations using a field emission scanning electron microscope and scanning probe microscope, the surface morphology of the films was found to depend chiefly on depositing time. All the films exhibit a high transmittance (>80%) in the visible region, except for the film deposited for 120 minutes. The band gap values of the ZnO films deposited for various time are found to be 3.25-3.27 eV.
