Abstract

Top emission organic EL devices were fabricated by using metal-doped cathode interface layer to achieve low drive voltages. Also, facing-targets-type sputtering was used to sputter indium-tin oxide layer on top of organic active layer. The devices fabricated in this study showed reasonably high external quantum efficiency of about 1 % which is comparable to that of bottom-emission-type devices.
