| titleOfInvention | Quantum dot surface ligand exchange method |
| abstract | Provided is a quantum dot surface ligand exchange method. The method comprises the steps: pre-treating proton-containing ligands using a deprotonating agent to obtain deprotonated ligands; mixing a pre-prepared quantum dot solution having original ligands with the deprotonated ligands, after stirring for a predetermined amount of time at room temperature, a ligand exchange reaction occurring, and after washing, obtaining a quantum dot having the deprotonated ligands on the surface. The quantum dot ligand exchange method has a high reaction rate and is easy to operate; after the ligand exchange, the deprotonated ligands firmly bind to cations on the surface of the quantum dot, and after the ligand exchange, the quantum dot provides a stable colloidal solution, and has good solubility and high luminous efficiency. |
