Effect of Sn-incorporation on the Structural and Optical Properties of ZnO Thin Films Prepared by Sol-Gel Method

Abstract

In this research, thin films of ZnO doped with Sn were prepared through the sol-gel method. The effects of Sn dopant on optical, morphological and structural studies were investigated. All of the films in this work showed favored orientation along the (002) plane, according to XRD analysis. It was observed by SEM analysis that the study Sn morphological and structural studies were investigated. From AFM pictures it is clear that as the doping concentration rises, the size of the grains on the surface of thin films decreases.The existence of Zn, O and Sn was verified by the EDAX analysis. The Ultraviolet-visible spectroscope was utilized to examine the optical characteristics. That band gap increased with the dopant material percent increased.
