Title:
QUANTUM DOT AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/199310
Kind Code:
A1
Abstract:
The present invention provides a quantum dot and a preparation method therefor. The preparation method for the quantum dot comprises: respectively preparing a first solution, a second solution, and a cesium oleate solution; mixing the first solution and the cesium oleate solution and making same react, so as to obtain a reaction solution; performing centrifugal separation on the reaction solution to obtain an intermediate quantum dot; and dispersing the intermediate quantum dot in the non-polar organic solvent, adding the second solution, making same react, so as to obtain a target quantum dot.
