摘要：

Bi2+-doped BaSO4 phosphor was synthesized in air via solid state reaction method. Three excitation bands and one emission band were observed at 260 nm (P-2(1/2) -> S-2(1/2)), 452 nm (P-2(1/2) -> P-2(3/2)(2)), 592 nm (P-2(1/2) -> P-2(3/2)(1)), and 627 nm (P-2(3/2)(1) -> P-2(1/2)), respectively. W-LEDs were demonstrated by using a blend composition of BaSO4:Bi2+ and YAG:Ce3+ phosphors pumped with a 455 nm blue LEDs chip. The results indicate that BaSO4:Bi2+ phosphor is suitable as potential red phosphor for application in W-LEDs excited with blue LEDs chip. (C) 2012 Optical Society of America
