Abstract
Ni-doped ZnO diluted magnetic semiconductors nanorods were successfully synthesized by hydrothermal method. The crystal structure, morphology, constituent elements and optical proprety of the products using this method were investigated via X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray energy dispersive spectrometry (XEDS) and ultraviolet-visible spectroscopy (UV-vis). The experiment results show that the morphology of samples were nanorods with good dispersion, all the diffraction peaks correspond to the wurtzite structure hexagonal phase, no other impurity phase appeare, and the Ni2+ions successfully substituted for the lattice site and generate single-phase Zn1-xNixO. The band gap increases firstly and reduces afterward with the increase of Ni2+contents.
