US 2026/0314160 A1 · METHOD FOR MANUFACTURING QUANTUM DOT, QUANTUM DOT, AND ELECTRONIC APPARATUS INCLUDING THE QUANTUM DOT

Abstract

A method for manufacturing a quantum dot including a core, which includes a multi-component system compound including Cu, In, Ga, and S, and a shell covering the core is provided. The method may include preparing a first mixture including a copper precursor and a metal catalyst, providing a first sulfur precursor to the first mixture to form a preliminary core, providing a second mixture including a gallium precursor and an indium precursor to the preliminary core at a first temperature, forming a core at a second temperature higher than the first temperature, and forming a shell covering the core. The metal catalyst may include at least one first component selected from among Ag, Au, Li, Na, and K.
