Abstract

Double hetero-structure electroluminescent (EL) devices with a cyanine dye LB film as an emitter were prepared. The cyanine dye formed J-aggregate in the LB film, and intense fluorescence with very narrow bandwidth was observed in the LB film. When DC voltage was applied to the devices, EL corresponded well with the resonance fluorescence of the J-aggregated cyanine dye. As a result of confinement of charge carriers and excitons within the cyanine dye emitter, efficient electroluminescence was attained even in the device with the J-aggregated cyanine dye bimolecular layer as an emitter.
