  • Systems and methods for improving the qualities of polymer light-emitting electrochemical cells
    Publication number: 20080303432
    Abstract: A light-emitting device comprising a pair of electrodes, and an emitting polymer active layer between the pair of electrodes, and either a) an electron transport layer, b) a hole transport layer, or c) a low work function material layer, wherein said emitting polymer layer comprising a single phase combination of a light-emitting polymer and an ionic liquid, is provided. Such multilayered devices have increased stability at relatively high voltages, fast turn-on times, low operating voltage, high brightness and long lifetimes.
