The effect of Co content on the magnetic and optical properties of Zn 1-xCoxOy nanorods have been investigated in this study. X-ray diffraction, energy dispersive spectrometer, photoluminescence and ferromagnetism measurements were used to characterize the Zn1-xCoxOy nanorods. It is shown that the ferromagnetic properties arise from the replacement of Zn by Co in the ZnO lattice. Combining with photoluminescence and scanning electron microscopic results, a direct link between the magnetization, nanorod sizes and acceptor defects of Zn1-xCoxOy nanorods was established.
