Description
Cadmium oxide (CdO) is a category of the practical semiconductor metal oxides, which is widely applied in various scientific and industrial fields because of its catalytic, optical, and electrical properties. CdO nanocrystal was successfully synthesized by a virtue of a single source precursor method at mild reaction conditions between cadmium oxide, and element iodine by a solvothermal route. X-ray powder diffraction (XRD), ultraviolet spectroscopy studies (UV-vis), Fourier Transform Infrared analysis (FTIR), scanning electron microscopy (SEM), μ-Raman spectroscopy and cyclic voltammogram (CV) were used to characterize the CdO nanocrystals. The ultra-violet visible absorption peaks of CdO exhibited a large blue shift and the luminescent spectra had a strong and broad emission band centered at 228 nm. The various functional groups present in the CdO nanocrystals were identified by FTIR analysis. Intense PL was also observed with some spectral tuning possibly giving a range of emission photon energies approximately spanning from 2.5 to 3.4 eV. Scanning electron microscopy and μ-Raman microscopy images indicated that the morphology of the product is spherical nanoparticles with an average particle size of 46 nm with standard deviation. The electrochemical response of CdO which is proved the nano-cadmium has high functionality due to the small size and it has higher electrochemical activity without any modifications. The above studies demonstrate the potential for the utilization of cadmium nitrite nanocrystal in visible opto-electronics applications. © 2014 Elsevier B.V. All rights reserved.
