Optochemical sensors find a huge number of applications with a great industrial demand. A typical organic optochemical sensor is composed of an organic light emitting device (OLED) as the light source and an organic photodiode (OPD) as the detection unit.

In this talk the results of the analytical characterization of such OPDs with regard to topography, roughness of the interfaces, and thicknesses of the layers will be presented. Therefore different techniques like transmission electron microscopy (TEM), scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray scattering techniques were used. The combination of these techniques form a nanoanalytical toolset well suited for the characterization of organic devices.
