In this work we analyze the characteristics of the ZnO film made by sol-gel pyrolytic nebulization, in terms of the variation of solvent composition. For this purpose, we present and discuss a characterization using macroscopic images of the films, X-ray diffraction (XRD) and UV-VIS-NIR transmittance spectroscopy. Among the relevant results, increase in the water/ethanol ratio was found to be related to an increase in film thickness. Furthermore, the thickness, coverage area and transparency of the film were also found to be dependent on the solvent composition of the starting solution. This study contributes to the understanding of the relationship between a major growth parameter such as the composition of the starting solution, and the desired characteristics of ZnO films that are relevant for technological applications.References
