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.

Method for producing a quantum dot

A method for producing coated semiconductor nanoparticles, comprising a step of coating the surface of semiconductor nanoparticles with a metal oxide, wherein the surface of the semiconductor nanoparticles is coated with the metal oxide by treating a metal oxide precursor with microwave irradiation treatment.

Coated semiconductor nanoparticles and method for producing the same

A quantum dot has a fluorescent crystalline nanoparticle, wherein the quantum dot has a core-shell structure including a core particle containing a first metal element and a shell layer containing a second metal element, at an interface between the core particle and the shell layer, a third metal element different from the first metal element and the second metal element is present, and an amount of the third metal element with respect to an amount of the first metal element contained in the core particle is 10% or less in terms of molar ratio. As a result the quantum dot has excellent controllability of the emission wavelength and high luminous properties and luminous efficiency.
