Title:
QUANTUM DOT BLUE LIGHT-BLOCKING MATERIAL AND PREPARATION METHOD THEREFOR, AND BLUE LIGHT-BLOCKING LENS, AND FILM
Document Type and Number:
WIPO Patent Application WO/2022/104640
Kind Code:
A1
Abstract:
The present invention relates to a quantum dot blue light-blocking material and a preparation method therefor, and a blue light-blocking lens, and a film. The quantum dot blue light-blocking material comprises a quantum dot material and a high molecular polymer material. The quantum dot material having mercaptan added is dispersed in the high molecular polymer material. The quantum dot material is a semiconductor nanocrystal used for absorbing blue light and having an absorption band edge of 440-470 nm, and is a Group II-VI compound, a Group III-V compound, a Group I-IV-VII compound, or an analogous Group I-IV-VII compound. The mercaptan refers to a non-aromatic compound containing a sulfhydryl functional group (-SH). The present invention has the technical effects such as efficient blue light absorption performance, almost no fluorescence, cheap raw materials, and easy preparation.
