| titleOfInvention | A kind of preparation method of quantum dot light-emitting diode |
| abstract | The invention discloses a preparation method of a quantum dot light emitting diode. The quantum dot light emitting diode is a positive type device. The method comprises the steps of: providing an anode; forming a hole function layer on the surface of the anode; and forming a hole function layer on the surface of the hole function layer A layer of short-chain ligand compounds is formed; a quantum dot light-emitting layer is formed on the surface of the short-chain ligand compounds. The invention can not only obtain stable quantum dots, but also can greatly improve the recombination of electron/hole pairs in excitons and improve device efficiency. Meanwhile, the ligand exchange method of the present invention has the advantages of simple steps, short operation time, and can effectively avoid the influence on other membrane layers. |
