AbstractZinc oxide (ZnO) thin film have been prepared by Spray Pyrolysis technique using zinc acetate dehydrate dissolved in methanol, ethanol and deionized water. A number of techniques including X-ray diffraction (XRD), optical transmission microscope (OTM), Fourier transform infrared (FTIR) spectroscopy, UV-visible were used to characterize and
study the obtained ZnO thin films. The evolution of preferred crystalline orientation in the ZnO films was systematically investigated and the (002) reflection was the preferred orientation. The optical measurement reveal that films have a maximum transmittance of about 90% and a direct band gap of 3.2 eV.
