Investigation on physical properties of nanosized copper oxide (CuO) doped with cobalt (Co): A material for electronic device application

Abstract This study has reported about the preparation and characterization of Copper oxide (CuO) nanoparticles doped with Cobalt series at low temperature by Sol‐gel method. The techniques like X‐ray diffraction (XRD), scanning electron microscope (SEM), Raman spectroscopy, defused reflectance spectroscopy (DRS), DC measurement have been used to confirm its phase formation, that is, monoclinic, surface porous morphology, redshift peaks confirms optical phonon confinement, whereas increasing bandgap signifies quantum confinement effect. semiconducting nature samples observed two probe Furthermore, focused in detail on effect cobalt doping varying concentrations wt % structural, morphological, optical, conductivity features.
