On November 18, 2023, the Photonic Nose and Molecular Materials Group held an academic seminar in the lecture hall of the Institute of New Concept Sensors and Molecular Materials, and Weng Yuxiang, a researcher from the Institute of Physics of the Chinese Academy of Sciences, presented a report titled “Development and Application of Ultrafast Time-resolved Spectroscopy”. Teachers and graduate students of the institute attended the seminar, which was moderated by Prof. Bian Hongtao.

Weng Yuxiang introduced the progress of his research group in equipment development, research methods and research systems in recent years. They have established a new method for measuring femtosecond time-resolved fluorescence spectra with single-photon fluorescence non-collinear optical parametric amplification, developed the measurement of coherent state energy transfer by femtosecond time-resolved two-dimensional electron spectrometer, expanded the application of transient infrared spectroscopy in the excitation scanning of intermediate energy levels in the band gap, studied the biological quantum effects in the membrane proteins of photosynthetic bacteria light-trapping antennas, and has been developing pulse temperature-nanosecond time-resolved transient mid-infrared spectroscopy.

After the report, Weng Yuxiang discussed relevant issues with the teachers and students present, and took a photo with the teachers.
