Abstract
The present invention is a method for producing perovskite type quantum dots, wherein, using a plurality of precursor solutions each containing a different element, each of the plurality of precursor solutions is heated and sprayed as an aerosol of the precursor solution, and the plurality of aerosols are collided to cause a gas phase reaction, dropping in a solvent to synthesize core particles containing the different elements. This provides a method for producing quantum dots that enables control of the particle size and yields nanoparticles with a uniform particle size even in large-scale synthesis.

A method for producing perovskite type quantum dots, wherein,
- using a plurality of precursor solutions each containing a different element, each of the plurality of precursor solutions is heated and sprayed as an aerosol of the precursor solution, and the plurality of aerosols are collided to cause a gas phase reaction, dropping in a solvent to terminate the gas phase reaction and synthesize core particles containing the different elements, wherein a temperature of the solvent is −10° C. to 20° C. and wherein the temperature of the solvent is lower than a temperature of the precursor solution.
