Figure 6From: Structure and properties of Co-doped ZnO films prepared by thermal oxidization under a high magnetic field XPS spectra of Co-doped ZnO films. (a) XPS survey scan spectra. High-resolution XPS of (b) Zn 2p, (c) O 1 s, and (d) Co 2p state energies. (e) Dependence of magnetic flux density on the relative area of oxygen vacancies versus O ions in (c).Back to article page
