Title:
METHOD FOR PREPARING QUANTUM DOT, AND QUANTUM DOT AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/168684
Kind Code:
A1
Abstract:
Provided are a method for preparing a quantum dot, and the quantum dot and a display device. The method comprises the following steps: providing a first precursor solution, a second precursor solution, a first selenium precursor solution, and a second selenium precursor solution having a lower reaction activity than the first selenium precursor solution; adding the first selenium precursor solution to the second precursor solution to form an intermediate of the quantum dot; and performing the following steps at least once to form the quantum dot: adding the first precursor solution and the second selenium precursor solution to the intermediate of the quantum dot and performing a reaction, without cleaning the intermediate of the quantum dot.
