Semiconductor nanoparticle having high luminescence properties comprising an electron-donor group and a multilayered coating comprising a hydrophobic group

摘要

Disclosed is a semiconductor nanoparticle having excellent chemical durability and high luminescence properties. The chemical durability of the particle is provided by coating the semiconductor nanoparticle having high luminescence properties dispersed in an organic solvent using a surface-active agent, an amphipathic molecule, and a lipid composed of a combination of two or more layers selected from a polar group, a hydrophobic group, a hydrophilic group, and a functional group (herein, the hydrophobic group is a necessary element and the hydrophilic group and the functional group are optional).
