摘要: Abstract Zn 0.91 Cu 0.04 M 0.05 O (M=Ni, Co, Cr) nanocrystals were successfully synthesized by co-precipitation method and the structural optical properties have been investigated. X-ray diffraction spectra showed that hexagonal wurtzite structure was not altered TM co-doping. Due to less solubility of Ni in Zn–O, NiO phase emerged Ni, co-doped ZnO nanocrystals. The change lattice parameters discussed corresponding radii doping element. surface morphology studied scanning electron microscope presence compositional elements such as Ni/Co/Cr, with their nominal stoichiometry confirmed energy dispersive spectra. shift band gap TM-doping based on strength sp–d spin-exchange interactions between electrons localized d-electron dopant.
