Phosphor and light emitting device using the phosphor |
| abstract |
An embodiment of the present invention provides a green light emitting phosphor having high quantum efficiency and a light emitting device having little color shift including the phosphor. The phosphor is generally represented by (Sr 1-V EU) 3- xy Al 3 + Zr Si 13- ZO 2 + u N 21 -w and is a Sr 3 Al 3 Si 13 O 2 N 21 phosphor. In addition, this phosphor exhibits an X-ray diffraction pattern having a diffraction peak having a 2θ of 15.2-15.5 °, and the half width thereof is 0.14 ° or less. In addition, the phosphor exhibits light emission having a peak within the wavelength of 490 to 580 nm when excited by light having a wavelength of 250 to 500 nm. Further, the light emitting device provided by the embodiment of the present invention includes a material combining a light emitting element and a red light emitting phosphor. |
