On May 12, 2023, Prof. Ma Xiaonan of Tianjin University was invited by the Photonic Nose and Molecular Materials Group to give a report to the group members in the Meeting Room 1568 of Zhi Zhi Building. The report was hosted by Prof. Ma Jiani and attended by group teachers and students.

Prof. Ma’s research interests include excited state dynamics detection in organic and perovskite semiconductors, excited state-light field interaction in optical microcavities, and micro-nanoscale excited state behavior regulation. In the report, he mainly introduced their recent research on the photophysical mechanisms of several emerging OLED materials based on femtosecond transient absorption spectroscopy experiments and thermal vibration correlation function methods, and revealed how these ultrafast mechanisms directly affect the subsequent slow relaxation process and play a positive regulatory role in OLED performance.

After the report, Prof. Ma discussed related issues with the teachers and students present, and took a photo with them.
