Document Type and Number:
WIPO Patent Application WO/2023/277326
Kind Code:
A1
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 a first mixture by mixing an organic phosphor and a surfactant; and (S2) preparing a dispersion by mixing the first mixture with a first solvent which is an anti-solvent for the organic phosphor.
