we demonstrate a unique method to quantum dots light emitting devices(QD-LEDs) based on nanoporous templates. Hexagonal array of P2VP cylinders oriented normal to the surface in thin films of polystyrene-block-poly(2-vinyl pyridine) copolymer is generated on a Zinc Oxide by solvent-annealing. Then nanopores in BCP thin films are produced as immersed in ethanol. By oxygen plasma, the nanoporous templates are fabricated on the ZnO layer. Hexagonal array of QDs is immediately produced as they are deposited from the QDs solution by spin-coating process. HTL, HIL, and Anode are deposited using CVD method. Finally, QD-LEDs based on hexagonal array of QDs is successfully fabricated and characterized. |
