Ultrafast Spectroscopy Laboratory

Ultrafast time-resolved laser spectroscopy mainly related to molecular excited
states, photochemical reactions, photocatalytic, energy and charge transfer
processes (including the primary process of photosynthesis, singlet fission,
artificial photovoltaic, light emitting devices, etc.), nanomaterials characterization,
protein folding kinetics, superconducting, spintronics and biomedicine. With the
development of ultrafast time-resolved laser spectroscopy, ultrafast molecular
dynamics process in the femtosecond time scale has become an important topic
for researchers. It plays a vital role in understanding the molecular structure and
properties. Since the molecular level of the solar light - based, optical - electrical
conversion, and research is an important research direction.
Our special approach is aimed on the investigation of photophysical processes
which are proceeding from upper excited electronic states. This research area is
in much extent remains unexplored. Ultrafast time-resolved laser spectroscopy
platform construction will address this research bottleneck, provide important
theoretical basis for the study of ultrafast molecular dynamics process in the field
of solar energy conversion and fine chemicals and new materials, producing more
world-class high-level scientific research.
This is a multidisciplinary laboratory which should stimulate collaboration between
research groups in various branches of natural science, i.e. optics, spectroscopy,
chemical physics, molecular biology, material science.

Techniques
Ultrafast spectroscopy laboratory will contain VIS-NIR pump-probe setup with 50
fs resolution, time-resolved fluorescence up-conversion setup with 100 fs
resolution, and time-correlated single photon counting technique for time-resolved
fluorescence measurements with 10 ps resolution. Various compounds would be able

to measure, i.e. solid state, in solvents, films, metal-organic frameworks,
organic crystals etc.
