  • NITRIDE PHOSPHOR AND METHOD FOR PRODUCING SAME
    Publication number: 20220315837
    Abstract: Provided a method for producing a nitride phosphor. The method includes preparing a mixture that comprises a first nitride and a cerium source, the first nitride comprising, as a host crystal, a crystal having the same crystal structure as CaAlSiN3; and performing a heat treatment of the mixture at a temperature of 1,300° C. to 1,900° C. to obtain a second nitride. The first nitride comprises aluminum, silicon, nitrogen, and at least one selected from the group consisting of lithium, calcium, and strontium.
