On March 23, 2026, Prof. Arkady Yartsev from Lund University in Sweden visited the Institute of New Concept Sensors and Molecular Materials at Shaanxi Normal University and presented a report titled “Time-Resolved Photophysics and Photochemistry in Transition Metal Complexes”.

Based on transient absorption spectroscopy, Prof. Yartsev systematically elucidated the detailed mechanisms of photophysical and photochemical processes in various transition-metal complexes by effectively suppressing artificial interference signals and conducting an in-depth analysis of the experimental data.

From March 24 to 26, Prof. Yartsev taught a seminar series titled “Time-Resolved Spectroscopy: Transient Absorption”, in which he explained the principles, testing methods, and data analysis of transient absorption spectroscopy, shared his valuable experience in the field, and engaged in research discussions with several graduate students at the institute.

The report and seminars were chaired by Prof. Ma Jiani. About 50 participants, including Prof. Fang Yu and faculty and students from the institute, attended the events and had discussions with Prof. Yartsev.
