Abstract
A method of producing semiconductor nanoparticles, semiconductor nanoparticles, and a light-emitting device are provided. The method includes heat-treating a mixture containing a salt of Ag, a salt containing at least one of In and Ga, an Se supply source, and an organic solvent at a temperature in the range of above 200° C. to 370° C. In the method, the ratio of the number of Ag atoms to the total number of In and Ga atoms in the mixture is above 0.43 to 2.5. The semiconductor nanoparticles contains Ag, at least one of In and Ga, and Se. The light-emitting device includes a light conversion member containing the semiconductor nanoparticles and a semiconductor light-emitting element.
