Research output: Chapter in Book/Report/Conference proceedingConference contribution


A novel red-emitting olivine-structure type phosphor NaMgP04:Eu2+was synthesized for the first time by the melt synthesis technique. The NaMgP04:Eu2+phosphor can be efficiently excited by blue light (450 nm) irradiation and presents red emission band centered at 628 nm. The internal quantum efficiency of this phosphor at the excitation wavelength of 450 nm was 81%.
