Quantum dot composition, resin composition, and wavelength conversion material

Abstract

A quantum dot composition including a quantum dot that emits fluorescence by excitation light, the quantum dot including a semiconductor nanoparticle core and a semiconductor nanoparticle shell that do not contain Cd and Pb, wherein a surface of the quantum dot is coated with a metal oxide, and the surface of the quantum dot or a surface of the metal oxide is modified with a phosphonic acid derivative. This provides a quantum dot composition that prevents reduction in the fluorescence emission efficiency despite using a low-toxicity quantum dot.
