Sol Sol-gel synthesis, structural and optical properties investigation of Ce4+ doped CdO sub-micron materials

Highly crystalline ce4+-doped cadmium oxide sub-micron structures were synthesized by calcinations of the obtained precursor of a sol-gel reaction. the reaction was carried out with cadmium nitrate (cd(no3)2.4h2o), cerium nitrate ce(no3)4.6h2o and ethylene glycol (c2h6o2) reactants without any additive at 80°c for 2h. resulting gel was calcined at 900 °c with increasing temperature rate of 15°c per minute for 12 h in a furnace. as a result of heating, the organic section of the gel was removed and ce4+-doped cadmium oxide micro structure was produced. the obtained material synthesized from the sol-gel technique, possesses a cubic crystalline structure at micro scale. x-ray diffraction (xrd) study indicates that the obtained ce4+-doped cdo has a cubic phase. sem images showed that the resulting material is composed of particles with cluster structure. other two techniques ft-ir and uv-vis spectroscopies were employed for further characterization of the ce4+-doped cdo micro structures.
