Abstract
We have grown the nanostructure Mn-doped CdO films by sol–gel spin coating method. The structural and morphology properties of the Mn doped CdO films were characterized by atomic force microscopy and X-ray diffraction method. The Mn doped CdO films are formed from the nanoparticles and the particle size is controlled with manganese content. The crystal structure of undoped and Mn-doped CdO films is a cubic sodium chloride structure, showing two main characteristic peaks assigned to the (111) and (200) planes. X-ray diffraction results indicate that the Mn doped CdO films are nanomaterials with an average crystallite size of 22–25nm. The optical band gap (Eg) values of undoped and Mn-doped CdO films were found to be in the range of 2.23–2.58eV and Eg values of the CdO films are increased with Mn dopant up to 6% Mn. The obtained results indicate that the structural and optical properties of the CdO film can be controlled by Mn doping.
