Study of Structural and Optical Properties of Cd Doped ZnO Thinfilms

Abstract

Transparent conducting Zinc oxide and Cadmium doped Zinc oxide thin films have been prepared on glass substrates using sol-gel spin coating technique. The effects of Cd addition on the structural and optical properties of ZnO thin film were investigated. The crystalline behavior of the Zinc oxide thin film was studied by X-ray diffraction (XRD). It has been found that the crystalline behavior of ZnO film reduced after the addition of Cadmium in ZnO lattice. The optical properties of Zinc Oxide thin film have been investigated by Photoluminescence spectrum. PL spectrum observed the violet and blue-green emissions of undoped and Cd-doped ZnO thin film.
