Structural and optical properties of chemically deposited Mn-doped ZnO thin films

Abstract

Pure ZnO and Mn-doped ZnO thin films were deposited by chemical bath deposition met for various Mn doping concentrations. The structural, morphological and optical properties of the prepared films were studied using various techniques. XRD analysis shows hexagonal structured ZnO for all films and peak shift is noticed for Mn-doped films. The crystallite size is found to be increased for Mn doping. The surface morphology of the Mn-doped film shows irregular shape particles that are agglomerated. The transmittance spectra show higher transmittance in the visible region and it decreased for Mn doping, which indicates an increase in optical absorption. The band gap of Mn-doped films is found to be decreasing with Mn doping. The Mn-doped films show higher optical and electrical conductivity in UV region.
