Method for producing β-sialon phosphor |
| abstract |
Provided is a method for producing a β-type sialon phosphor capable of improving the luminescence intensity without adding metal elements other than the elements constituting the β-type sialon phosphor. That is, in the method for producing a phosphor containing an optically active element as a light emitting center in the crystal of nitride or oxynitride, a firing step of heating a mixture containing a metal compound powder and an optically active element compound, and cooling the fired product Thereafter, a β-type sialon phosphor is produced by a high temperature annealing step of performing heat treatment in a nitrogen atmosphere, a rare gas annealing step of heating a high temperature annealing treated product under a rare gas atmosphere, and a step of treating the rare gas treated product with an acid. |
