Abstract

Zn0.96−x Co0.04Cu x O (0 ≤ x ≤ 0.1) nanopowders were successfully synthesized by sol–gel method. Hexagonal structure was confirmed by X-ray diffraction spectra. A new phase around 38.4° corresponding to CuO was noticed after Cu = 4 %. The reduced crystal size up to Cu = 4 % is due to the substitution of Cu2+ and the increasing crystal size after Cu = 4 % is due to the interference between Co and Cu metal ions. The higher absorption of Cu doped Zn0.96Co0.04O than undoped was due to the created charge carries. The tuning of energy gap from 3.18 to 3.69 eV by Cu-doping was discussed in terms of crystal size, the created charge carriers and the interstitial zinc atoms and oxygen deficiencies. Presence of chemical bonding and purity of the nanopowders were confirmed by Fourier transform infrared spectra.
