Abstract

Zn.96-xY.04CuxO (x = 0, 0.05, 0.10 and 0.15) nanoparticles were successfully synthesized employing simple sol-gel method. Hexagonal wurtzite structure of the synthesized samples was not affected by Cu-doping. CuO phase was induced after Cu = 5% and it was increased by Cu-doping. The change in crystal size was discussed based on compressive stress, lattice volume and bond length. The chemical stoichiometry of Zn, Cu, Y and O was confirmed by energy dispersive X-ray spectra. The increased oxygen percentage from 57.88 (Cu = 5%) to 64.53% (Cu = 15%) by Cu-doping proved the existence of CuO and oxygen rich phase. The lower absorption and high transmittance in visible region observed at Cu = 5% de..
