Effect of crystal structure of chemically grown Zinc Oxide thin film on optical properties.

Amongst various metal oxides, Zinc Oxide (ZnO) draws the attention of the scientific community for its various types of properties. For this study purpose, ZnO thin films were prepared by Modified Chemical Bath Deposition (MCBD) technique. To remove out the formation of excessive hydroxide, the bath temperature was maintained at 80°C.There was no change in crystallinity in case of pristine sample. As the annealing temperature increased, the crystallinity goes on improving and then after decreased as it was depicted in the structural morphologies and the variation in the optical properties were also in good correlation with the structural morphologies.
