Preparation method of quantum dot, quantum dot, quantum dot composition and color film |
| abstract |
The present application provides a method for preparing quantum dots, which includes the steps of: providing hydrophobic ligand-modified quantum dots; mixing and reacting the hydrophobic ligand-modified quantum dots with amphiphilic ligands, wherein, The amphiphilic ligand includes a coordinating group combined with the nanocrystal and a hydrophilic group connected to the coordinating group; the hydrophobic ligand and the quantum dot modified by the amphiphilic ligand are obtained . Amphiphilic ligands can improve the good compatibility between quantum dots and polymer materials, make quantum dots better dispersed in polymer materials, avoid the phenomenon of quantum dots agglomerating in polymer materials, and amphiphilic ligands The bonding to the quantum dot surface through the coordination group is very stable, thereby improving the stability and optical performance of the quantum dot. |
