In this research, zinc oxide semiconductor nanoparticles doped with copper and iron elements were synthesized by the reverse co-precipitation method and their electrical and magnetic properties were investigated. The results of XRD analysis of ZnO nanoparticles showed that high-purity nanoparticles were produced, and the presence of the added dopants did not change the hexagonal structure of zinc oxide despite the slight changes in crystallite size. Besides, the results of the FESEM analysis revealed the morphology and the size of 25 nm for the nanoparticles. Furthermore, the results of PL and DRS-UV analysis showed that the band gap and optical and electrical properties of the dopant zinc oxide nanoparticles have been enhanced compared to the zinc oxide. Finally, the magnetic characteristics of these nanoparticles was investigated using the VSM analysis, and the results showed appropriate ferromagnetic properties. In conclusion, the results demonstrate the success of the reverse co-deposition method by using a non-ionic surfactant (Span 80) in the production of Cu2+- doped and Fe2+- doped ZnO nanoparticles.
