Influences of Dopant Concentration on Crystallography, Optical and Electrical Properties of Cadmium Oxide Nanoparticles

Abstract

Influences of Dopant Concentration on Crystallography, Optical and Electrical Properties of Cadmium Oxide Nanoparticles Cadmium oxide (CdO) nanoparticles doped with different amount of rare earth metal Neodymium (Nd) ions have been prepared by Chemical co precipitation method. The doping level was varied from [Nd/Cd] = 0.1 to 10 wt%. Crystallography analysis of these materials is carried out by X- ray diffraction (XRD) which reveals that average crystalline size is in nano region i.e. 30-30.8 nm. The synthesized nanomaterial was characterized by means of X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier transformation infrared spectroscopy (FTIR), UV-Visible Spectroscopy (UV-Vis). Electrical properties were also studied as a function of dopant concentration. Present studies also investigate the effect of varying dopant concentration on morphology and topography of as prepared nanomaterial.
