Tom Vosch has a background in single molecule fluorescence microscopy and spectroscopy. During his PhD, he studied the fluorescent properties of rylene labeled dendrimers at the single molecule level, resulting in the demonstration of several Förster type energy transfer processes like energy hopping, singlet-singlet annihilation and singlet-triplet annihilation at the single molecule level. As a postdoctoral fellow, he got interested in the unique fluorescence properties of small noble metal clusters and their applications in life and material sciences. He also initiated research leading to the discovery of bright photo stable fluorescent silver clusters in zeolites. These materials can find applications in solar cells, fluorescent lamps, LEDs and optical storage devices. His research group at the University of Copenhagen is mainly focussed on noble metal cluster fluorescence and single molecule fluorescence spectroscopy.
The group has built up single molecule fluorescence detection techniques (confocal piezo scanning and wide field), fluorescence correlation spectroscopy, micro-Raman spectroscopy and time-correlated single photon counting techniques. The group consists currently out of 1 associate professor, 2 PhD students and 2 Postdoctoral fellow.
