摘要： There has been a problem in that kinds of conventional light-emitting materials are not sufficient; therefore, choices of materials and manufacturers of light emitting materials are limited, resulting in an expensive light-emitting device. The present invention provides a novel method for manufacturing a light-emitting material suitable for mass production that can be manufactured at a low cost, and a novel light-emitting material which can provide light emission with high intensity. A mixture in which CuAlS2 is added in a small amount into ZnS as a base material is put in a reaction container. Then, the reaction container is hermetically sealed and the mixture is baked. Note that the reaction container is preferably hermetically sealed in a state where a reduced pressure is held in the reaction container. Further, in a light-emitting element using a light-emitting material obtained, electroluminescence with high luminance can be obtained.
