Abstract :
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
