Title:
OXYNITRIDE PHOSPHOR POWDER
Document Type and Number:
WIPO Patent Application WO/2014/192694
Kind Code:
A1
Abstract:
Provided is an oxynitride phosphor powder, which 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. This oxynitride phosphor powder is obtained from an α-SiAlON represented by the compositional formula:
Cax1Eux2Ybx3Si12-(y+z)Al(y+z)OzN16-z
(wherein 0.0 < x1 ≤ 2.0, 0.0000 < x2 ≤ 0.0100, 0.0000 < x3 ≤ 0.0100, 0.4 ≤ x2/x3 ≤ 1.4, 1.0 ≤ y ≤ 4.0, 0.5 ≤ z ≤ 2.0).
