In this study, we demonstrate unique method to fabricate quantum dots light emitting devices(QD-LEDs) using nanoporous templates from directed self-assembly (DSA) of asymmetric block copolymers (BCPs) on large area. ZnO nanopillars was fabricated the just spin-coating process on the nanoporous templates and formed nano-pillar array of ZnO playing a role of ETL. The solution of QDs/solvent is spin-coated on ZnO layer to fabricate the QDs monolayer that becomes the EML. HTL, HIL, and Anode are sequentially deposited using vacuum evaporation. Finally, the QD-LEDs based on nanoporous templates are successfully fabricated and characterized. |
