ß-SIALON PHOSPHOR, USES THEREOF, PROCESS FOR PRODUCTION OF ß-SIALON PHOSPHOR |
| 摘要 |
<p>The present invention provides a ²-SiAlON phosphor that contains a ²-SiAlON represented by a general formula Si 6-z Al z O z N 8-z (0<z<4.2) as a matrix and Eu 2+ in a form of a solid solution as an emission center, and exhibits a peak within a wavelength range from 520 to 560 nm when excited by blue light. The average diffuse reflectance of this ²-SiAlON phosphor in the wavelength range from 700 to 800 nm is 90% or higher, and the diffuse reflectance in the fluorescent peak wavelength is 85% or higher.</p> |
