摘要：

In this letter, a yellow oxynitride phosphor alpha-SiAlON with compositions of Ca0.625EuxSi0.75-3xAl1.25+3xOxN16-x ( Ca-alpha-SiAlON:Eu, x=0-25) was prepared by gas pressure sintering. The diffuse reflection spectrum, photoluminescence spectrum, and chromaticity of the powder phosphors were presented. It absorbs light efficiently in the UV-visible spectral region, and shows a single intense broadband emission at 583-603 nm. This phosphor may become a good candidate for creating white light, typically warm white light, when coupled to a blue light-emitting diode (lambda(em)=450 nm).
