Abstract：A novel broadband emission phosphor Sr3-2xLi1+xMgV3O12∶xEu3+ was synthesized by a solid-state reaction method. Then discussed the luminous property under the influence of temperature and doping density of Eu3+, was discussed. X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence spectra were used to characterize the feature of Sr3-2xLi1+xMgV3O12∶xEu3+. The excitation and emission spectra exhibit that the phosphor of Sr<sub>3-2xLi1+xMgV3O12∶xEu3+ matches with nearly ultraviolet chip. The emission band covers from 450 to 630 nm, which shows that the phosphor is promising single-phase phosphors for white LED.
