| titleOfInvention | A surface-treated perovskite nanocrystal and its preparation method and application |
| abstract | The invention provides a surface-treated perovskite nanocrystal and a preparation method and application thereof. The preparation method includes: mixing perovskite nanocrystals and ligands at room temperature, and performing a ligand exchange reaction to obtain the surface-treated perovskite nanocrystals; the ligands include salts containing sulfonic acid groups, Or a combination of a sulfonic acid-containing acid and an amine-based compound. By combining the method for preparing perovskite nanocrystals with ligand exchange, the present invention neutralizes the acid containing a sulfonic acid group with an amine compound or directly utilizes a highly stable sulfonic acid group ligand formed by a salt containing a sulfonic acid group Replacing the original ligands on the surface of nanocrystals can greatly enhance the lattice bonding force between the ligands and perovskite nanocrystals. At the same time, the whole process does not require high temperature and inert atmosphere, and the reaction can be performed at room temperature without toxic solvents, saving energy. cost. The perovskite nanocrystals prepared by the invention have high stability, strong repeatability, and are environmentally friendly and can be scaled up for production. |
