We report the preparation of Zn<SUB>1-x</SUB>Ni<SUB>x</SUB>O nanorods through a chemical route using microwave irradiation. The obtained Zn<SUB>1-x</SUB>Ni<SUB>x</SUB>O nanorods were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), Raman spectroscopy and magnetization measurements. XRD and TEM results showed that the Zn<SUB>1-x</SUB>Ni<SUB>x</SUB>O nanorods have single phase nature with wurtzite structure and Ni was successfully incorporated at Zn site into the ZnO. The shape of the nanorods changed from hexagon (length ~1.5 μm, diameter ~200 nm) to pencil like tip (length ~1 μm, diameter ~80 nm) by only changing the Ni content from 1% to 3% in ZnO. Concerning the Raman scattering spectra, the modification in the intensity of E<SUB>2</SUB><SUP>high</SUP> mode and sub-band edge emissions provides enough evidence for the existence of intrinsic defects associated with the O atoms. Magnetic measurement results revealed that Zn<SUB>1-x</SUB>Ni<SUB>x</SUB>O nanorods show the well-defined ferromagnetic features at room temperature and the value of M<SUB>s</SUB> increased with the increase of Ni concentration.
