Phosphor, Method of Manufacturing the Same, and Lighting Equipment Using the Same |
abstract |
The phosphor has a particle diameter distribution measured by a laser diffraction scattering method, wherein β-sialon represented by the general formula: Si 6-Z Al Z 0 Z N 8-Z is a parent material, and is employed by Eu as a luminescent center. Is a powder having a 10% diameter (D 10 ) of 7 to 20 μm and a 90% diameter (D 90 ) of 50 to 90 μm in an integrated fraction, and a phosphor having a low decrease in fluorescence intensity and a luminaire using the phosphor Can be provided. This phosphor can be produced by maintaining a silicon nitride powder and an aluminum nitride powder, a raw material powder obtained by mixing an aluminum-containing compound and an Eu-containing compound, if necessary, at a temperature of 1,850 to 2,050 ° C for at least 9 hours in a nitrogen atmosphere or a non-oxidizing atmosphere. . |
