Phosphor powders, composites and light emitting devices |
| abstract |
A certain aspect of the present invention is a phosphor powder comprising α-sialon phosphor particles containing Eu. The phosphor powder has a volume-based median diameter (D 50 ) of 10 µm or more and 20 µm or less according to a laser diffraction scattering method, and a diffuse reflectance of 93% or more and 99% or less with respect to light having a wavelength of 600 nm. |
