Abstract
A method for producing a β-sialon fluorescent material is provided. The method includes heat-treating a mixture containing an aluminum compound, a first europium compound, and silicon nitride to obtain a first heat-treated product; and heat-treating the first heat-treated product with a second europium compound in a rare gas atmosphere to obtain a second heat-treated product.
