Title:
METHOD FOR PRODUCING QUANTUM DOT, AND ORGANIC PHOSPHINE
Document Type and Number:
WIPO Patent Application WO/2018/084262
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method whereby it becomes possible to produce a quantum dot having a narrow grain size distribution with high reproducibility even when an amino-substituted organic phosphine precursor is used in the synthesis of the quantum dot. The method for producing a quantum dot according to one aspect of the present invention comprises a step of mixing a Group-IIIB precursor with an organic phosphine precursor to produce a precursor mixture and a step of heating the precursor mixture to produce a solution of a Group-IIIB phosphide quantum dot, wherein the organic phosphine precursor has one or multiple amino substituents, and at least one of parent amines for the amino substituents has a boiling point of 160ºC or higher under the standard atmospheric pressure.
