Synthesis and characterization of Ce3+ doped CdO nanoparticles via sol-gel method

The nanoparticles CdO and Ce3+doped CdO was successfully synthesized via a low temperature (900°C)by sol- gel method using Cd(NO(3))(2) and Ce2(NO(3))(3) as starting materials and ethylene glycol as astabilizer. CdO has a cubic system with a=b=c=4.695Å. The SEM micrographs indicate that with adding and changing the amount of Ce3+ the morphology of the obtained material changed and indicate that the CdO is consisted of nanoparticles with grain size of 150-300 nm. The structural properties of the CdO were investigated by X-ray diffraction (XRD). XRD patterns show that with doping the Ce3+ element, the obtained phase is isostructural with the pure CdO materials. It is evaluated that this work is useful as a basis for the search of nanomaterial CdO and more competitive Ce3+- CdO based electrical properties.
