Abstract
A method for producing a phosphor made of luminous inorganic particles of a nanostructure which is capable of keeping a surface of the phosphor from being polluted by any by-product and controlling a particle diameter distribution of the phosphor as desired. A carbon material and an inorganic salt are mixed together to prepare a mixture, which is then heated, to thereby form an interlaminar compound. Then, the interlaminar compound is subject to a treatment using an eliminating agent, leading to production of luminous inorganic compound particles adhered to the carbon material.
