In this paper, spin coating process is adopted for the preparation of thin films of ZnO over the glass substrate. The key components used for the fabrication of ZnO solution are zinc acetate dehydrate, 2-Methoxy ethanol and mono ethanol amine. Structural morphology of the samples are estimated using the technique of XRD (X-ray Diffraction) and SEM (Scanning Electron microscopy) respectively. The results indicates that precise control of reactance, spinning speed and heat treatment of the films have great impact on the crystal growth and orientation. The XRD results demonstrates c-axis orientation of ZnO film, having the preferred peak along (002) plane and the grain size is 15.8 nm. the optical transmittance spectrum reviles that the average value of transmittance is about 95% and bandgap is assessed to be 3.34 eV.
