Abstract |
|
Cadmium oxide nanoparticles were prepared using modified precipitation method using cadmium chloride and ethanol solution. The particle size of CdO nanoparticles is found to be 41nm using x-ray diffrometer. UV visible found absorption peak appeared at 300nm. This absorption band of CdO nanoparticle has been shows a blue shift due to quantum confinement. Photoluminescence (PL) spectrum shows band edge emission at 396nm and green emission at 548nm. Green emissions arise from the oxygen vacancy of cdo material because of photo generated hole in valance band with an electron in conduction band. |
