Abstract
The present invention is a method for producing a light-emitting body containing silicon fine particles that emit visible light, comprising: a baking step of baking a mixture containing a silicon source and a carbon source in an inert atmosphere; a rapid cooling step of rapidly cooling a gas generated by baking the mixture to obtain a composite powder; and a removing step of removing a portion of the composite powder, wherein in the removing step, a portion of silicon monoxide and a portion of silicon dioxide are removed from the composite powder containing silicon fine particles, silicon monoxide, and silicon dioxide.
