摘要	Diluted magnetic semiconductors Zn1-2xFexNixO with different consistency ratio (x=0, 0.025, 0.05, 0.1) have been synthesized by hydrothermal method.The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and X-ray energy dispersive spectrometry (XEDS), and the optical and magnetic properties of the products were investigated by Raman scattering spectra (Raman), photoluminescence spectra (PL) and vibrating sample magnetometer (VSM).The experiment results show that all samples synthesized by this method possess wurtzite structure with good crystallization, no other impurity phase appeared, and the morphology are nanorods and well dispersed. All the Fe2+ and Ni2+ successfully substituted for the lattice site of Zn2+ and generate single-phase Zn1-2xFexNixO, Raman spectra occurred red shift and the photoluminescence intensity were quenched due to the crystal defects and internal stress increase with iron and nickel co-doping. In addition, the obvious ferromagnetic was found in all samples at room temperature, and the saturation magnetization enhanced with the increase of iron and nickel doping content.
