Red phosphor and light-emitting device |
| abstract |
A phosphor whose main crystal phase has the same crystal structure as CaAlSiN 3 and a part of Ca element is replaced by Eu element, the median particle diameter d50 of the phosphor measured by a laser diffraction scattering method is 12.0 μm or more and 22.0 μm or less, the specific surface area measured by the BET method is 1.50 m 2 /g or more and 10.00 m 2 /g or less. |
