Photonic quasi crystals to enhance light extraction efficiency for White OLEDs applications

In this paper we realized different PQCs polymeric anodes PEDOT:PSS based (octagonal, dodecagonal and Thue-Morse patterns) using a high-resolution electron beam lithography (EBL) technique. We characterized and selected photonic quasi crystal structures that could enhance the efficiency of a polymeric based White Organic Light Emitting Diode (WOLED) device onto the nanostructured highly conductive PEDOT:PSS polymer electrode.
