| Abstract(in English) | A novel red-emitting Eu^<2+>-activated olivine-type NaMgPO_4 phosphor was synthesized by a melt synthesis technique using arc-imaging furnace. The NaMgPO_4:Eu^<2+> phosphor can be efficiency excited by blue light irradiation, and presents red emitting band centered at 628 nm due to the 4f^65d^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 under the excitation wavelength of 450 nm was 81%. Furthermore, these phosphors show an excellent thermal stability on the temperature quenching effect. |
