摘要

Sr3 (Al2 O5) Cl2 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 ∼400 nm. Yellow light-emitting diodes (LEDs) for general lighting were fabricated by combining Sr3 (Al2 O5) Cl2: Eu2+ phosphor with an NUV chip. The phosphor-converted LEDs had a color temperature of about 2300 K and their color rendering index was 74.
