Abstract

A quantum dot including a semiconductor crystal particle having a particle diameter of 20 nm or less, and a ligand having two or more functional groups for interaction with the semiconductor crystal particle coordinates to two or more sites on a surface of the semiconductor crystal particle. A quantum dot with enhanced stability through surface modification on the semiconductor crystal particle by using a ligand which has two or more functional groups for interaction with the semiconductor crystal particle, and which coordinates to two or more sites on the semiconductor particle surface.
