Abstract
The nanocrystalline ZnO thin films were successfully prepared via the sol-gel spin coating method for the different atomic ratios Mn doping (0,1%, 0,5%, 1%, 2%, 5%). The detailed surface analysis of samples was performed by Atomic Force Microscopy (AFM). The AFM results indicate that the ZnO films have the nanostructure. The morphological characteristics of films show that Mn2+ ions are included in the crystal lattice of ZnO without changing the structure. The influence of the Mn doping on the film growth is resulted in a increase of fiber size and roughness. The fiber size values of the films were found to vary from 0.898µm to 2.960 µm with Mn doping. The study revealed the possibility with Mn doping of controlling, optimizing and improving the morphology in ZnO thin-film production.
