Abstract

A novel red-emitting olivine-type NaMgPO₄:Eu²⁺ phosphor was synthesized for the first time by the melt synthesis technique using arc-imaging furnace. The NaMgPO₄:Eu²⁺ phosphor can be efficiently excited by blue light irradiation and presents red emission band centered at 628 nm due to the 4f⁶5d¹ → 4f⁷ transition of Eu²⁺. The highest emission peak intensity was obtained for NaMgPO₄:2.5mol%Eu²⁺, 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.
