Title:
METHOD FOR PRODUCING SEMICONDUCTOR NANOPARTICLES, AND SEMICONDUCTOR NANOPARTICLES
Document Type and Number:
WIPO Patent Application WO/2023/119960
Kind Code:
A1
Abstract:
This method for producing semiconductor nanoparticles comprises a step for preparing a precursor solution by mixing a Zn ion source solution and a Te ion source solution; and a step for heating the precursor solution in an air-tight container. In the step for preparing a precursor solution, the pH of the precursor solution is controlled at 5 to 9, and in the step for preparing the precursor solution and the step for heating the precursor solution, oxygen is removed from the precursor solution such that the oxygen concentration in the precursor solution is at most 2 mg/L.
