제목 Enhancement of Device Efficiency in Hybrid Polymer Light Emitting Diodes by Surface Modification of Metal Oxide
초록 To date, several approaches have been exploited to promote electron injection by interfacial modification between the electron injection layer and emissive polymer layer. Electrodes with cesium carbonate (CS2CO3), metal fluoride, conjugated polyelectrolytes, ionic polymers, and radiative surface treatment of electrodes have been reported to improve electron injection so far. Here, we present a method to remarkably enhance the electron injection efficiency of HyPLEDs by the surface modification of ZnO using self-assembled dipole molecules (SADMs) and ionic liquid. As a consequence, the HyPLEDs modified with a negative dipolar SADM and ionic liquid exhibited remarkably improved electroluminescence efficiency and luminance.
