ABSTRACTThe external quantum efficiency in conventional double-layer type organic light-emitting devices with different layer thickness was carefully evaluated. From the measurements of luminance and emission spectra, external quantum efficiency (uncorrected) was obtained.The correction due to the modification of spatial emission distribution was added from the measurements of spatial emission patterns. The external quantum efficiency, both uncorrected and corrected, showed strong dependency on the distance between a metal electrode and an emissive region. This variation was ascribed to the change of coupling-out efficiency. Independent experimental evaluations of apparent couple-out efficiency using an integrating sphere supported this interpretation.
