Abstract:
Provided is a method for manufacturing a semiconductor nanoparticle, the method includes performing a heat treatment of a first mixture containing a silver (Ag) salt, an alkali metal salt, a salt containing at least one of indium (In) and gallium (Ga), a sulfur source, and an organic solvent. A ratio of the number of atoms of an alkali metal to the total number of atoms of Ag and the alkali metal in the first mixture is greater than 0 and less than 1.
