The present invention attempts to solve the problem of providing a method for producing light-emitting particles whereby it is possible to produce, at a high yield, light-emitting particles that have high stability with respect to moisture, light, and heat and in which light emission wavelength and particle size are controlled. The present invention also addresses the problem of providing a method for producing a composition containing the light-emitting particles. The present invention provides a method for producing light-emitting particles that comprise a core including semiconductor nanoparticles and a ligand layer bonded to the core via an amino group, in which the ligand layer includes a siloxane bond, and wherein the method comprises a step in which at least one first liquid containing a production starting material or a precursor of light-emitting particles and at least one second liquid having different components from the first liquid and containing the production starting material or the precursor
