Research Profile:
a) techniques
· time-resolved spectroscopy (femtosecond transient absorption, fluorescence up-conversion, streak-camera fluorescence detection, single-photon counting, flash photolysis)
· hole-burning spectroscopy (absorption, excitation and fluorescence hole-burning)
· low-temperature spectroscopy (experience with spectroscopic measurements in the temperature range down to 1.5 K)
b) studied systems
· carotenoids in solution (excited state dynamics, charge-transfer states, triplet states, radicals, aggregates)
· carotenoids in proteins (light-harvesting, photoprotection, radical formation)
· carotenoids in artificial systems (carotenoid as an electron donor in donor-acceptor systems)
· photosynthetic light-harvesting proteins (excitation energy transfer, excitons, polarons)
· supramolecular donor-acceptor systems designed for mimicking natural photosynthesis (electron and energy transfer processes)
· dendrimeric and supramolecular heterometallic systems designed to act as artificial antennae (energy migration within the artificial antennae)
· semiconductor based solar cells (studies of electron injection and recombination processes at the TiO2-dye interface)
