摘要：

The Eu2+-activated Sr2Mg3P4O15 (Sr2Mg3P4O15: Eu2+) phosphor is prepared using solid-state reactions of SrCO3, MgO, (NH4)(2)HPO4, and Eu2O3. The phosphor is excited efficiently by near-ultraviolet (n-UV) light irradiation, showing bright blue emission spectra at wavelengths of 400-550 nm with a maximum peak of 447 nm. The temperature dependence of luminescence intensity for (Sr0.94Eu0.06)(2)Mg3P4O15 is higher than that of commercial (Y, Gd)(3)Al5O12: Ce3+. In fact, Sr2Mg3P4O15: Eu2+ has high
