In this study, nanostructured ZnO thin film coatings produced by sol-gel method have been examined and characterized. ZnO thin film coatings synthesized by the preparation of ZnO sols in the liquid phase from homogeneous solutions with precursor of zinc acetate dihydrate (Zn(CH3COO)2·2H2O). Ethanol (C2H5OH) has been used as a solvent material and monoethanolamine (MEA) has been used as a complexing agent. The final solutions have 0.1, 0.3, 0.5, 0.7 and 1 molar concentrations. General morphologies and detailed structural characterizations have been obtained by using scanning electron microscope (SEM). Qualitative analyses of the synthesized coatings were performed using X-ray diffraction (XRD) and Raman spectroscopy. The Raman spectroscopy studies of precursor, solution and final products were carried out to investigate transformation of the chemical compounds from the initial material to the final coating.
