The activities of our laboratory aim at a detailed description of photo-induced processes in the molecular condensed phase (liquid, solid and proteins) and in metallic and semiconductor nanostructured materials. A central approach of our group is the visualization in "real time" of the processes by means of ultrafast laser spectroscopy.
The physical phenomena we investigate include: solvation dynamics in polar media, at interfaces and within proteins, structural changes in the chromophores and the medium (be it a solvent or a protein) and the influence of local electric fields on their spectral and dynamical features. We also study the ultrafast dynamics of charge carriers in semiconductor and metallic nanostructures of different shapes and sizes.
The experimental tools we use are ultrafast picosecond and femtosecond transient absorption spectroscopy, ultrafast fluorescence up-conversion spectroscopy, photon-echo spectroscopy. We have also developed novel optical laser pump-X-ray probe techniques using picosecond and femtosecond hard X-ray pulses from a synchrotron.
