Our research is focussing on developing new physical chemistry methods for the analysis of complex samples and the development of new optical materials. The methods are based on microscopic and spectroscopic techniques such as single-molecule microscopy, fluorescence correlation spectroscopy, two-photon microscopy, super-resolution microscopy, ultrafast spectroscopy and non-linear spectroscopy. The materials developed are based on various organic molecules and nanoparticles with distinct optical properties and embedded in host materials such as polymers. On important focus is the development of materials containing nanodots, nanorods, nanoplatelets and different organic molecules at well-defined distances and orientations to enable new functions such as directed excitonic flow through pigment networks. Another important focus is light-redirecting for applications in fields related to energy conversion, optological circuits, fiber lasers and telecommunication.
