摘要：

Sr-3(Al2O5)Cl-2 phosphor doped with Eu2+ was prepared by a soli-state reaction. This phosphor emits a broad orange-yellow luminescence with a peak wavelength of 620 nm and a full width at half maximum of about 175 nm under near-ultraviolet (NUV) excitation at similar to 400 nm. Yellow light-emitting diodes (LEDs) for general lighting were fabricated by combining Sr-3(Al2O5)Cl-2:Eu2+ hosphor with an NUV chip. The phosphor-converted LEDs had a color temperature of about 2300 K and their color rendering index was 74. (C) 2008 American Institute of Physics.
