Phosphor and light emitting device using the same |
| abstract |
Provided are a phosphor with high quantum efficiency and a light emitting device using the same with little color shift. A general formula (Sr 1-x Eu x) 3-y Al 3 + z Si 13-z O 2 + having a composition represented by u N 21-w, Sr 3 Al 3 Si 13 O 2 N 21 genera phosphor In the X-ray diffraction pattern of the phosphor, light having a diffraction peak position 2θ of 15.2 to 15.5 ° and a half width of 0.14 ° or less and a wavelength of 250 to 500 nm A phosphor that emits light having a peak between wavelengths of 490 and 580 nm when excited with. In addition, a light emitting device in which this phosphor, a red phosphor and a light emitting element are combined. [Selection] Figure 1 |
