High-Resolution Patterning of Quantum Dots via Azide-Containing Hole Transporting Polymeric Ligand |
| 초록 |
Despite rapid advances of colloidal quantum dots (QDs) in terms of facile synthetic method and superb optical quality, cutting-edge patterning technology is continuously required which enable QDs to be realized into display devices with high-definition. In this work, we report one-step patterning methodology which does not requires complicated surface treatment, soft-hard baking, or lift-off processes. Multifunctional photo-crosslinkable & hole transporting polymeric ligands are grafted and simple photolithography step is conducted, resulting in extremely uniform full-colored QD micro-patterns. We also demonstrated possibility of extended application into the patterning of various nanomaterials such as metal nanoparticles and perovskite nanocrystals. We believe that our simplified approach suggest alternative patterning technology for the optical and optoelectronic devices. |
