The authors have fabricated organic electroluminescent (EL) diodes with a microcavity structure designed to have a resonance wavelength of 500 nm, by using a metal reflector and various dielectric reflectors. The emission intensity (spectral power density) is enhanced by a factor of 5 compared to that of an EL diode without a cavity, and narrow spectral width of 8 nm was achieved in blue green emission.

Inspec keywords: cavity resonators; spectral line breadth; electroluminescent devices; optical resonators; organic semiconductors; light emitting diodes

Other keywords: spectral power density; EL diodes; dielectric reflectors; spectral width; blue-green emission; microcavities; organic electroluminescent diodes; emission intensity enhancement; metal reflector; 500 nm
