Method for producing a quantum dot

Abstract

A method for producing a quantum dot including crystalline nanoparticle fluorescent material, wherein, using a first precursor solution and a second precursor solution containing different elements each other, the second precursor solution is sprayed as an aerosol on the heated first precursor solution, or both the first precursor solution and the second precursor solution are sprayed on a heated solvent as aerosols, and the first precursor solution and the second precursor solution are reacted with each other to synthesize a core particle containing the different elements. The method for producing quantum dots, can suppress the non-uniformity of the particle size of the quantum dots and accompany increase in the distribution of emission wavelengths in large scale synthesis.
