Abstract
Zn1-xCoxO(x=0–10at%) films were prepared using the spray pyrolysis method at 723 K on glass substrates. The structural and transport properties of Zn1-xCoxO deposits were studied using X-ray Diffraction(XRD), Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS), UV-VIS Spectrophotometer and Vibrating Sample Magnetometer (VSM). XRD analysis confirmed a hexagonal wurtzite-type structure with a preferential orientation in the (0 0 2) plane, indicating Co2+ ion in the ZnO host matrix, and absence of secondary phase of the metals in the ZnO host matrix. The surface morphology modified from fibrous to spherical grain shape with enrichment of cobalt in the deposits. The composition analysis indicates the existence of Zinc and Cobalt. The XPS analysis provides the do pantexistsin Co2+ state.
