The successful operation of the experimental platform fills the gap in the field of femtosecond dynamics research of Dalian University of Technology, and provides the dual-class construction of Dalian University of Technology, and enhances the scientific research level of Dalian University of Technology such as photophysics, photochemistry, biology, and materials. Strong technical support.
The femtosecond spectral experimental platform has two main functions. On the one hand, based on the pump-probe method, it can perform transient absorption measurements of molecules or materials in the UV-Visible and infrared regions. The resolution can reach 30 fs (1fs=10-15s); on the other hand, it can also be used. Time-correlated single-photon counting (resolution 10 ps, ​​1 ps = 10-12 s), fluorescence emission up-time of molecules or materials was measured using fluorescence up-conversion (resolution 100 fs).
At present, the platform can monitor the ultra-fast kinetic relaxation process of dye-sensitized solar cells, perovskite solar cells, functional dyes, organic crystals, and nanomaterials in real time. The successful establishment of the femtosecond spectral experimental platform provides the possibility for deeper rapid reactions such as ultrafast photoinduced electron transfer and energy transfer at Dalian University of Technology.
Dr. Gagik Gurzadyan, Professor, PhD supervisor, born in 1957. Dr. Moscow State University has conducted research work at the Max Planck Institute, Humboldt University in Berlin, Germany, Munich University of Technology in Germany, the French Institute of Atomic Energy in Sacré, and Nanyang Technological University in Singapore. In view of Professor Gurzadyan’s efforts in ultra-fast time-resolved laser spectroscopy, nonlinear spectroscopy and other research fields with high academic and international influence, Professor Sun Licheng, the head of the “Artificial Photosynthesis Research Institute†of the Research Institute of Dalian University of Technology, worked hard. Next, Prof. Gurzadyan was invited to join Dalian University of Technology on September 2015 to work on femtosecond spectroscopy. After more than a year of unremitting efforts, the Dalian University of Technology successfully established the platform and achieved a breakthrough in the field of femtosecond dynamics research at Dalian University of Technology.
(Original title: The first femtosecond spectrum measurement platform of Dalian University of Technology was established and put into operation)
[China Instrument Network Instrument R&D] Recently, the State Key Laboratory of Fine Chemicals has successfully established the first (second Liaoning Province) femtosecond time-resolved spectrum measurement platform of Dalian University of Technology. This platform is mainly composed of the first synthesis of Dalian University of Technology. Professor Gagik Gurzadyan of the “Artificial Photosynthesis Research Institute†in the reform pilot area was responsible for the completion of the construction.
