Abstract
A method for providing a phosphor, including a kneading step in which a raw material is kneaded to provide a raw material mixture; a sintering step in which the raw material mixture is sintered; and a heat treatment step in which the sintered raw material mixture is heat-treated, wherein the raw material includes at least one or more M-containing materials selected from MSi2, MSiN2, M2Si5N8, M3Al2N4 and MSi6N8, wherein M is one or more divalent elements selected from M(0) and M(1).
Claims4
A method for producing a phosphor, the method comprising:
