- Abstract
We prepared Codoped ZnO films by the electrochemical deposition. Xray diffraction XRD, high resolution transmission microscopy HRTEM, xray photoelectron spectroscopy XPS, atomic force microscope AFM, xray absorption nearedge structure XANES, vibrating sample magnetometer VSM, optical absorption, and photoluminescence PL measurements were carried out on the samples. The results showed Co atoms substituted Zn atoms in the ZnO lattice without the formation of the impurity phase. VSM measurements showed the ferromagnetic properties for the Codoped ZnO samples. When the Co doping concentration increased, the band gaps were widened and the PL peak positions shifted towards the short wavelength direction. © 2009 WILEYVCH Verlag GmbH & Co. KGaA, Weinheim
