Fluorescent powder, composite and light emitting device |
| abstract |
PROBLEM TO BE SOLVED: To provide a technique relating to a phosphor powder having improved light emitting characteristics. One aspect of the present invention is a phosphor powder composed of α-type sialone phosphor particles containing Eu. When the internal quantum efficiency of the phosphor powder after being held at 600 ° C. for 1 hour in an air atmosphere is P1, and the internal quantum efficiency after being held at 700 ° C. for 1 hour in an air atmosphere is P2, P1 is It is 70% or more, and (P1-P2) / P1 × 100 is 2.8% or less.
