摘要ZnO(0.95)Co(0.05) O and Zn(0.94) Co(0.05) Al(0.01) films were prepared by inductively coupled plasma enhanced physical vapor deposition with magnetic confinement system under different oxygen partial pressure. The local structure and charge transfer properties were investigated by X-ray absorption fine structure and resonant inelastic scattering spectroscopy at O-K, Co-K and Co-L edges. The Co K-edge and L-edge X-ray absorption fine structure revealed that Co(2+) ions substituted for tetrahedrally coordinated Zn(2+) ions without changing the wurtzite structure. The main defects were oxygen vacancies when the films were deposited under very low oxygen partial pressure. The resonant inelastic scattering spectroscopy indicated that the charge transfer between Co-3d and the electrons in Zn(0.94) Co(0.05) Al(0.01) O films was much stronger than that in Zn(0.95) Co(0.05) O. The oxygen partial pressure had an important effect in the charge transfer of Co-doped ZnO films.
