Organic optoelectronics
Light emitting diodes (OLEDs), and photo detectors (OPDs) based on organic semiconductor materials can be monolithically integrated on very different substrates. This provides the ability to directly integrate compact, cost-effective optoelectronic units into microfluidic chips. Figure 1 shows a macroscopic test system for this concept. We explore the miniaturisation of such optical reader units for micro-integration and use in sensors. For this purpose, we develop OLEDs and OPDs in the Kiel Nanolaboratory. Our speciality is the use of nanostructuring for customising the radiation characteristics of OLEDs. This is particularly interesting for miniaturised sensor systems, for optimum utilisation of light.
