摘要：
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 4f(6)5d(1) -> 4f(7) 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. (C) 2013 The Electrochemical Society. All rights reserved.
