Synthesis and Characterization of Pure and Magnesium (Mg) Doped CuO Nano Particles by Solid State Method

Abstract

Pure and Magnesium (Mg) doped CuO nanoparticles were effectively prepared by solid state method using Copper Chloride (CuCl2 · 2H2O), Magnesium Chloride (MgCl2 · 6H2O) and Sodium Hydroxide (NaOH). The ITO/TiO2/CuO–M/Cu heterojunctions solutions were fabricated by Dr Blade method at a low reaction temperature of 400 °C. In this analysis the prepared nanostructure were exposed to structural, morphological and optical analysis. The X-ray diffraction peaks results divulged that the prepared nanoparticles are monoclinic structure of CuO which was evidenced from the JCPDS card No. 801916. Morphological analysis result exposed that pure CuO particles exclusively consist of agglomerated irregular spherical shape. The result of the elemental analysis confirmed the presence of Mg2+ in the doped samples. Fourier Transform Infra-Red Spectroscopy results reveals the structural modifications due to the presence of magnesium. Optical absorption measurement spectra demonstrates that band gap shift is due the proportion of Mg.
