The effect of Eu-loading on the some physical features of CdO
Source abstract
Abstract
Abstract The Eu-loaded CdO thin films were coated on the glass substrates with a sol-gel spin coating method by using Cd(CH3COO)2·2H2O and EuCl3·6H2O salts. The effect of Eu-loading ratio varied from 0 to 4 at% in the step of 1 at% on the structural, morphological, electrical, and optical features of cadmium oxide had been evaluated with XRD, Raman study, SEM, AFM, Four Point Probe, and UV/VIS analysis. The coated films were polycrystalline with (111) preferential orientation and they had a cubic cadmium oxide structure. The granular-structure was observed from SEM and AFM images. The sizes of granules were in the range of 15–220 nm. It was observed that the homogeneity of granule distribution deteriorated with Eu-content. The RMS roughness value increased from 4.1nm to 284 nm with Eu-doping. The minimum sheet resistance was found to be 4.8 × 102 Ω for 2 at% Eu-content, but the maximum optical band gap was determined to be 2.61 eV for 1 at% Eu-content. The Urbach energy varied between 366 meV and 658 meV. As a result of this work, Eu-doping has an important effect on the properties of cadmium oxide.
