Abstract：In order to improve the luminescence intensity and decrease the synthesis temperature of ZnO∶Eu3+ phosphors, the single-phase ZnO∶Eu3+ luminescent material was prepared with the high-temperature mechanic-chemical (HTMC) method.The structure, microscopic morphology and luminescence properties of samples were characterized with the scanning electron microscope (SEM), X ray diffractometer (XRD) and fluorescent spectrometer.The results show that the optimum reaction temperature of ZnO∶Eu3+ phosphors is 450℃, and the optimum ball-milling time is 3h.When the mole fraction of Eu3+ is 2.5％ and the ball material ratio is 20∶1, the optimum luminescence intensity of ZnO∶Eu3+ phosphors can be obtained after ball milling for 3h at 450℃.
