We report on the characterization of ternary Zn1–xCoxO alloy crystalline films grown by electrodeposition onto FTO-coated substrates. The Zn1–xCoxO films have hexagonal wurtzite structure as shown by X-ray diffraction measurements. The Co incorporation into the ZnO lattice is confirmed by the presence of absorption peaks assigned to Co in trigonal crystal field. X-ray photoemission spectroscopy indicates that as-grown films have a considerable concentration of not-fully oxidized metallic Co in the surface that correlates with the O concentration in the surface. Finally, Raman measurements of as-grown films indicate that they are polycrystalline with grains of nanometric size showing short-range order but no long-range order. The Raman spectra show no trace of first-order phonons and resemble the one-and two-phonon density of states of ZnO (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
