• We fabricated submicrometer-sized organic light emitting diodes (OLED) with bright emission using a poly-mer blend. The cell structure was composed of ITO (indium-tin oxide)/hole transport layer (polymer blendlayer)/emitter layer/MgAg. We used poly (methyl methacrylate) (PMMA) as an inert host material and N,N'-diphenyl-N,N'-bis(3-methylphenyl)-[1, l'-biphenyl]-4,4'-diamine-polycarbonate (PC-TPD) as a guest material. The PC-TPD formed submicrometer-sized spherical domains, actually prolate spheroids, in the PMMA hostlayer. With 2 wt% of PC-TPD, the domain diameters were around 200 um according to atomic force microscopy(AFM) observation. The OLED including such a blend structure appeared as an array of bright submicrometer-sized electroluminescence spots. The number of working diodes exceeded four million per square centimeter.
