PROBLEM TO BE SOLVED: To provide an illuminant with a high emission intensity and a wide range of light emission spectrum. SOLUTION: The illuminant is produced in the following processes, a process preparing a porous silicon 600, a process forming carbon clusters 630 in pores 612 formed in the porous silicon 600 prepared, and a process selectively oxidizing silicon 614 of the porous silicon 600 with carbon clusters 630 formed.
