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.
