Phosphor, light emitting device, and method of manufacturing phosphor |
| abstract |
It is an object of the present invention to provide a phosphor capable of obtaining high luminous efficiency even at high temperatures. The phosphor of the embodiment contains particles containing Sr 3 Si 13 Al 3 O 2 N 21 crystal activated by Eu, and has a wavelength of 490 to 490 when excited with light having a wavelength of 250 to 500 nm. Emission having an emission peak between 580 nm is shown. The particles have an average value (O outer ) of oxygen concentration in the crystal in the outer region up to 5 nm from the surface of the powder, and an average value (O outer ) of oxygen concentration in the crystal in the inner region deeper than 5 nm from the surface. inner) and the ratio of (O outer / O inner) is characterized in that it is a 1.0 to 3.8.
