The antimony-doped nano-zinc oxide was prepared after the nano-zinc oxide was doped with rare earth by direct precipitation method.The products were analyzed and characterized by X-ray diffraction,scanning electron microscopy and solid-state fluorescence spectroscopy.The effect of doping on the phase,crystal structure and fluorescence properties of zinc oxide was investigated,which was applied to the photocatalytic degradation of rhodamine B in wastewater.The results showed that Nd doping could greatly improve the photocatalytic performance of nano-ZnO under mercury lamp irradiation.With the increase of doping amount,the photocatalytic degradation performance of doped ZnO nanomaterials increased gradually.The removal rate of Rhodamine B by 7%（amount-of substance fraction） Nd-doped nano-ZnO was 89.62%.
