Title:
QUANTUM DOTS COATED BY METAL ION PAIR COMPOSITE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/218310
Kind Code:
A1
Abstract:
The present invention relates to quantum dots coated by a metal ion pair composite and a preparation method therefor. Quantum dots are pretreated by an alkyl compound (X-R) to create sites for metal ion growth on the surface of quantum dots, a corresponding metal salt is then added to grow the metal ion pair composite by means of a two-phase method, and after the reaction is carried out for a period of time, quantum dots coated by the metal ion pair composite are obtained. Compared with the prior art, the prepared quantum dots coated with the metal ion pair composite have excellent light stability and chemical stability.
