Abstract: A method for producing a sialon phosphor is provided. The method includes mixing a silicon precursor and an aluminum precursor and sintering the mixture to form a first sintered body. The first sintered body and a precursor for an active material are mixed and the mixture is heat-treated to form a second sintered body. That is, the exemplary method for producing a sialon phosphor involves firstly forming the first sintered body serving as a host material to stably ensure a crystal structure, and then mixing the active material and the first sintered body so as to preserve the role of the active material without sacrificing the crystal structure of the first sintered body.
