Fluorescence-Detected Pump–Probe Spectroscopy

Time-resolved spectroscopy enables ultrafast processes of chemical dynamics to be understood. Some limitations of traditional pump-probe spectroscopy are overcome by the newly developed fluorescence-detected pump-probe (F-PP) spectroscopy. 

Dr. Pavel Maly, postdoc with a fellowship from the Alexander von Humboldt Foundation, has developed the new F-PP with Prof. Dr. Tobias Brixner. F-PP suppresses excited-state absorption, provides background-free detection, removes artifacts, to name just a few advantages of the technique. This is made possible by combining sensitive fluorescence detection with ultrafast pulse-limited time resolution. This approach provides a complementary technique to standard transient absorption.

The functional principle of F-PP including theoretical description as well as a comparison with traditional pump-probe spectroscopy are described by the authors in their paper Fluorescence-detected Pump-Probe Spectroscopy in the journal Angewandte Chemie.
