Abstract

Eu2+ and Mn2+ codoped, white-emitting Na(Sr,Ba)PO4 phosphors are prepared, and their emission properties, especially for thermal stability, are thoroughly investigated. The thermal quenching and Eu2+/Mn2+ energy transfer efficiency are totally different in the ratio of alkaline earth metals in host composition, NaBaPO4, Na(Sr0.5Ba0.5)PO4, and NaSrPO4, respectively. Furthermore, by using near-ultraviolet light-emitting diodes (LEDs) and the corresponding Na(Sr0.5Ba0.5)PO4:Eu2+, Mn2+ phosphor as light converters, we demonstrate a bright and thermally stable white-emitting LED. The resultant LED exhibits a warm white light [4900K, CIE coordinates of (0.33, 0.31)] with excellent thermal and hydrolytic stabilities comparable to those of commercially available ones, Y3Al5O12:Ce3+ and BaMg2Al16O27:Eu2+. The proposed composition, with its efficient energy transfer, could enable Eu2+ and Mn2+ codoped Na(Sr,Ba)PO4 to be a promising single component phosphor for cost-effective white-emitting LEDs.
