Ferromagnetic and luminescence properties of Zn1−xMnxOy nanorods

The effect of Mn content on the ferromagnetic and luminescence properties of Zn1−xMnxOy nanorods have been investigated in this study. X-ray diffraction, x-ray photoelectron spectroscopy, energy dispersive spectrometer, photoluminescence and ferromagnetism measurements were used to characterize the Zn1−xMnxOy nanorods. It is shown that the ferromagnetic properties arise from the replacement of Zn by Mn in the ZnO lattice based on diamagnetic behavior for pure ZnO nanorods. On the other hand, combining with photoluminescence and scanning electron microscopic results, a direct link between the magnetization, nanorod sizes and acceptor defects of Zn1−xMnxOy nanorods was established.
