The reaction was carried out with cadmium nitrate (Cd(NO₃)₂.4H₂O), bismuth nitrate (Bi(NO₃)₃.5H₂O) and ethylene glycol (C₂H₆O₂) reactants without any additives 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 gel was removed and Bi³⁺-doped cadmium oxide micro structure was produced. The obtained compound from the sol-gel technique possesses a cubic crystalline structure at micro scale. Powder x-ray diffraction (PXRD) study indicated that the obtained Bi³⁺-doped CdO has a cubic phase. Also, SEM images showed that the resulting material is composed of particles with the average diameter of 1 µm. Also, UV–vis and FT-IR spectroscopies were employed to characterize the Bi³⁺-doped CdO micro structures. https://jns.kashanu.ac.ir/article_5441_c2840cbd17394e3fc41098e9b9801c1d.pdf
