Abstract:
An oxynitride phosphor powder is an α-SiAlON phosphor having a dominant wavelength of 565-577 nm and fluorescence intensity and external quantum efficiency that are high enough for practical use. The oxynitride phosphor powder comprises an α-SiAlON represented by the compositional formula: Cax1Eux2Ybx3Si12−(y+z)Al(y+z)OzN16−z (wherein 0.0
