The Structural and Optical Properties of Al Doped ZnO Thin Film

Abstract:

Al doped ZnO thin film have been prepared by a sol-gel method. The structural, and optical properties of the sample were investigated. X-ray diffraction and X-ray absorption spectroscopy analyses and UV absorption spectroscopy analyses indicate that Al³⁺ substitute for Zn²⁺ without changing the wurtzite structure. With the Al doping, the visible emission increased and the UV emission decreased, which is attributed to the increase of O vacancies and Zn interstitials.
