Fluorescent powder, complex, and light emission device |
| abstract |
One mode of the present invention is a fluorescent powder comprising α-sialon fluorescent particles containing Eu. Regarding the fluorescent powder, when the internal quantum efficiency after being retained at 600°C for 1 hour in an atmospheric environment is defined as P1 and the internal quantum efficiency after being retained at 700°C for 1 hour in an atmospheric environment is defined as P2, P1 is 70% or more and (P1-P2)/P1×100 equals 2.8% or less. |
