Zusammenfassung:A method of manufacturing -SiAlON represented by a general formula Si6-zAlzOzN8-z:Eu, including a baking step for baking a powdered material that contains Al content from 0.3 to 1.2 mass %, O content from 0.15 to 1 mass %, O/Al molar ratio from 0.9 to 1.3, Si content from 58 to 60 mass %, N content from 37 to 40 mass %, N/Si molar ratio from 1.25 to 1.45, and Eu content from 0.3 to 0.7 mass %. The baking step is a step of baking the powdered material in a nitrogen atmosphere at temperatures from 1850° C. to 2050° C., and the manufactured -SiAlON satisfies 0.280 x 0.340 and 0.630 y 0.675 on the CIExy chromaticity coordinate.
