Abstract: The SrWO4：Eu3＋ red phosphors with different Eu3＋ doping concentrations and different sintering temperatures are prepared by the co-precipitation method.The powders as-prepared exhibit sharply red characteristic emissions of Eu3＋ ions at room temperature.The near-ultraviolet and blue light absorption intensities are controlled by adjusting sintering temperature and doping concentration and so the red emission intensities under the 395 or 465 nm excitation can be adjusted.Our results show that the SrWO4：Eu3＋ red phosphors can be effectively excited by the ultraviolet light,the near-ultraviolet （395 nm） light and 465 nm blue light.Therefore the SrWO4：Eu3＋ red phosphors may have a potential application to white light-emitting diodes.
