Mn-doped ZnO films were prepared by radio frequency magnetron sputtering on sapphire substrate at different temperatures.They contained Mn of 5 at.%
without any magnetic impurities of Fe
Co and Ni
as were revealed by proton induced X-ray emission(PIXE).Synchrotron radiation X-ray diffraction(SR-XRD) showed that the ZnO:Mn films possessed the wurtzite ZnO structure.No precipitates such as Mn cluster or MnO
MnO2
Mn2O3
and Mn3O4were observed by SR-XRD and fluorescence extended X-ray absorption fine structure spectra(EXAFS) in ZnO:Mn films.EXAFS analysis also showed that Mn atoms were incorporated into ZnO crystal lattice by occupying the sites of zinc atoms.
