Abstract: A novel red-emitting olivine-type NaMgPO 4 :Eu 2+ phosphor was synthesized for the first time by the melt synthesis technique using arc-imaging furnace. The NaMgPO 4 :Eu 2+ phosphor can be efficiently excited by blue light irradiation and presents red emission band centered at 628 nm due to the 4f 6 5d 1 → 4f 7 transition of Eu 2+ . The highest emission peak intensity was obtained for NaMgPO 4 :2.5mol%Eu 2+ , and the internal quantum efficiency of this phosphor at the excitation wavelength of 450 nm was 81%. Furthermore, these phosphors show an excellent thermal stability on the temperature quenching effect.
