D3 - Orientation, outcoupling and emission shaping in templated molecular layers
Principle Investigator: Prof. Malte Gather
This project will harness the uniform molecular orientation in films of fluorescent J-aggregates and the spectrally narrow luminescence of the J-aggregate state, e.g. in merocyanine dyes. Our goal is to integrate J-aggregates as emissive layer in Organic Light-emitting Diodes and to harness their molecular orientation (B1) and photophysics, in combination with strong-light matter coupling architectures and/or optical gratings, to obtain efficient light extraction as well as spectrally narrow and highly directed emission.
