Patent ID: 7910400

Claim:
A method of fabricating a quantum dot electroluminescence device comprising: forming an anode electrode on an insulating substrate; forming a hole transfer layer composed of p-type polymer semiconductor on the anode electrode; two-dimensionally arraying synthesized quantum dots on the hole transfer layer to form a quantum dot luminescence layer; applying a cross-link agent to the quantum dot luminescence layer so as to cross-link the quantum dots and improve a chemical stability of the quantum dot luminescence layer; performing a wet chemical process on the quantum dot luminescence layer so as to form an electron transfer layer; and forming a cathode electrode on the electron transfer layer, wherein the cross-linking comprises supplying the quantum dot luminescence layer into a solution including the cross-link agent and heating under an inert gas ambient to maintain for a predetermined time, wherein the electron transfer layer is formed by a wet-processed thin film formation which includes coating on top of the quantum dot luminescent layer with a precursor solution including a precursor material and an organic solvent wherein the precursor material is organo-titanate or organo-zirconate, and performing a thermal curing treatment.
