Research Abstract

A significant increase in the quantum efficiency of an organic red- and blue-light-emitting diode was achieved through coupling with localized surface plasmons of Au nanorods and nanospheres, respectively, embedded on the substrate anode. We used Alq3 as an emission layer. The fabricated diode structure consists of an indium tin oxide (ITO) anode, a Cu phthalocyanine (CuPc) hole transport layer, an Alq3 electron transport layer, a LiF electron injection layer, and an Al cathode. We observed at most a 20-fold increase in the intensity of molecular fluorescence compared with that of a conventional diode structure.
