Photophysics and ultra-fast phenomena are about the interactions of light and matters, including the nonlinear responses of the matters to light; ultra-fast processes in from physics, chemistry, biology, medicine, and material science; the vibration and rotation of single molecule, liquid or lattice; the fracture and form of chemical bonds; vibrational relaxation of charge carrier in Quantum wires, quantum dots and nano crystals; energy transfer in photosynthetic unit, etc. The researches in this field are realized with nonlinear spectrometry, time-resolved absorption spectrometry, and time-resolved fluorescence spectrometry. Specific researches include:
1. Degenerate four-wave mixing spectrometry and application
2. Pump-probe ultra-fast spectrometry and application
3. Energy transfer in photosynthetic unit
4. Ultrafast magnetooptical effect and dynamics
