Ultrafast Spectroscopy laboratory – LEUR

We investigated the energy transfer mechanisms down to the biomolecular level in living and artificial energy conversion systems.  The nature of the energy transfer process requires extremely short interaction times being necessary to employ coherent light pulsed in the pico- and femtoseconds regime in two sections by separated rooms. The first, to characterize the fluorescence emission process as a molecular signature to different complexes in the nanosecond scale. And the second, to resolve measurements in faster processes in femtosecond scales, e.g. the lifetime of the intramolecular charge-transfer states.
