Light and Surfaces
Table of contents
a) Precursor development
Printing inorganic materials requires the development of molecular precursors with engineered viscosity, wetting behavior and a thermal conversion mechanism into the targeted metal or oxide material without the formation of carbon side products (Fig. 1). The team has developed customized precursors for platinum, silver, gold and oxide coatings (TiO2, SnO2:Sb, etc.) with high transparency and conductivity.

c) Nanostructured surfaces
We use nanoimprint technology and µ-contact printing in combination with sol-gel and precursor chemistry for the generation of nanostructured surfaces. We achieve high transparency and high electronic conductivity for optoelectronic applications. Light management is an important target for OLEDs. The periodicity of the surface can tune the efficiency and color of the flat display. Interdigital printed electrodes are ideal components for electrochemical sensors.
