Properties of the sandwiched electroluminescent layer (see graphic) of organic light emitting diodes (OLEDs) depend strongly on the ease of charge injection from the adjoining electrodes. Here, a procedure to achieve optimized efficiencies by controlled doping of a polymeric hole injection layer (PEDOT) is presented.
