Organic light-emitting diodes containing a liquid emitting layer that exhibit improved external electroluminescence quantum efficiency (Î∥EL) and maximum luminance are presented. Doping the liquid emitting layer with an electrolyte significantly decreases the turn-on voltage for electroluminescence. Insertion of a TiO2 hole-blocking layer between the liquid emitting layer and indium tin oxide cathode improves Î∥EL.
