The structural, optical, and thermal properties of undoped and Fe-doped CdO powder nanostructures prepared by the Co-precipitate calcinations method have been investigated. X-ray diffraction (XRD) results revealed that pure and Fe-doped CdO has polycrystalline with a face-centered cubic (FCC) structure. The crystallite size for undoped and $1,$ 5, 10, 15, 20, $30%$ of Fe-doped CdO samples were 44.25, 46.08, 65.66, 56.56, 50.1, 44.58, and $60.06 {nm}$, respectively. The optical band gap of the samples was determined from the diffused reflectance spectra, and $E_{g}$ values for undoped and $1,5,10,15,20,30%$ of Fe-doped CdO samples were found to be 1.978, 2.044, 2.024, 1.96, 1.92, 1.859, $1.88 {eV}$, respectively. The thermal stability of pure and Fe-doped CdO was measured by a thermogravimetric analyzer (TGA) in the temperature range from room temperature to 1000 at $15 {deg/min}$. The magnetic properties were investigated by VSM and ESR analysis which proves the promising magnetic performance employed for future applications.
