Abstract

Disclosed is a method for producing a semiconductor nanoparticle, which is a liquid phase method using a reaction liquid containing a semiconductor precursor. This method for producing a semiconductor nanoparticle is characterized in that a semiconductor nanoparticle is formed from the semiconductor precursor by irradiating the reaction liquid containing the semiconductor precursor with an ultrasonic wave. This method enables to obtain a core-shell semiconductor nanoparticle which exhibits high luminous efficiency when used as a light-emitting material.
