The embodiment provides a process for production of a green light-emitting oxynitride fluorescent material having Sr 3 Al 3 Si 13 O 2 N 21 crystal structure, and also provides the fluorescent material produced by that process. An metal halide is adopted in the process as one of the starting material metal compounds. As the metal halide, a Ca or Na compound as well as a Sr compound can be preferably employed. |
