Abstract: Provided is a method for manufacturing small and uniform light-emission type organic nanoparticles with improved yield. The method for manufacturing light-emission type organic nanoparticles according to the present invention comprises the steps of: (S1) preparing the first mixture by mixing an organic phosphor and a surfactant; and (S2) preparing a dispersion solution by mixing the first mixture with the first solvent which is an anti-solvent for the organic phosphor.
