Samples were annealed at different temperatures after 3 times coating. Crystallite size and the dislocation density of ZnO layers were evaluated by X-ray diffraction line broadening analysis. The morphology of samples was studied using SEM images Band gap transition spectra obtained through samples, and the relationship between the absorption edge in the absorption spectra of the samples with the results obtained from the analysis of the diffraction lines and their morphology was studied.
