Abstract

A self-organized, microstructured organic electroluminescent device was prepared. To form (sub)micrometer-sized dewetted patches ('domes') of a hole transport material on an indium-tin-oxide electrode, a dewetting process was used. It was shown that domes are regular in size and spacing. The results show that evaporation of an electron transport material and a Mg/Ag top electrode leads to a device with electroluminescing spots of micrometer dimensions and a spacing of a few micrometers.
