Surface plasmons limit the efficiency of organic light-emitting diodes (OLEDs). Up to 40 % of the radiative power may be lost to surface plasmon (SP) modes associated with the metallic cathodes of OLEDs. Calculations show the importance of material selection and device geometry in this process. Experiments reveal the presence of the SP modes and suggest ways in which this power may be recovered using periodic nanostructure.
