Abstract :
Highly crystalline Gd3+-doped cadmium oxide micro-structure was synthesized by calcining the obtained precursor
of a sol–gel reaction. The reaction was carried out with cadmium nitrate (Cd(NO3)2·4H2O), gadolinium oxide, and
ethylene glycol (C2H6O2) reactants without any additives at 80°C for 2 h. The resulting gel was calcined at 900°C with
increasing temperature rate of 15°C/min for 12 h in a furnace. As a result of heating, the organic section of the gel was
removed, and the Gd3+-doped cadmium oxide micro-structure was produced. The obtained compound from the
sol–gel technique possesses a cubic crystalline structure at a micro scale. XRD study indicates that the obtained
Gd3+-doped CdO has a cubic phase. Also, the SEM images showed that the resulting material is composed of particles
with cluster structure. Also, FT-IR spectroscopy was employed to characterize the Gd3+-doped CdO micro-structures.
