Abstract
Surface plasmon polariton (SPP)-enhanced blue phosphorescent organic light-emitting diodes (OLEDs) are demonstrated by inserting a thin Ag sublayer into the electron-transporting layer. An 18% improvement in current efficiency is achieved when the Ag sublayer locates at a suitable position between the light-emitting layer and the metal cathode. The improved efficiency was attributed to the effective energy transfer between excitons and SPP in OLEDs. Both experimental facts and theoretical simulation indicate that the SPP effect is associated with not only the emissive material and the inserted Ag sublayer, but also the metallic cathode that was paid little attention before.
