Title:

SEMICONDUCTOR NANOPARTICLES COMPOSED OF AGAUS-BASED MULTI-ELEMENT COMPOUND

Document Type and Number:

WIPO Patent Application WO/2023/149392

Kind Code:

A1

Abstract:

The present invention relates to semiconductor nanoparticles composed of a compound containing Ag, Au, S, and a metal M as essential constituent elements. In the present invention, the metal M is at least one of Al, Ga, In, Tl, Zn, Cd, Hg, and Cu, and the total content value for Ag, Au, S, and the metal M in the compound is 95 mass% or greater. Additionally, the ratio (x/(x+y)) of the number of atoms of Ag to the total of the number x of atoms of Ag and the number y of atoms of Au is preferably 0.50-0.88 inclusive. These semiconductor nanoparticles have biocompatibility as well as suitable light emission/absorption characteristics.
