Abstract
The present study report is on synthesis and characterization of cadmium oxide nanoparticles (CdO) which were prepared by the microwave irradiation method. The prepared nanoparticles were characterized by various techniques such as X-ray diffraction, Fourier transforms infrared spectroscopy, scanning electron microscope, energy dispersive spectroscopy, transmission electron microscope, ultraviolet visible diffuse reflectance spectroscopy, and photoluminescence techniques. The CdO nanoparticles are found to be cubic in structure from its XRD pattern. The average particle size was calculated from XRD analysis, which varies from 37 to 19 nm. The nail shaped morphology was confirmed by TEM analysis. Linear optical studies were used to determine the band gap energy of CdO nanoparticles. The DC electrical conductivity studies described the annealed CdO have a maximum conductivity compared to as prepared. The nail shaped CdO nanostructure was coated on the p-Si substrate using jet nebulizer spray pyrolysis technique. The fabricated Ag/n-CdO/p-Si diode parameters were evaluated in darkness and below different light sources such as Halogen and Metal halide lamps.
