Advanced Application of a Novel Femtosecond-Resolved Ultra-Broadband Ir Spectroscopy(1/2)

This proposal is intended to develop a novel femtosecond-resolved ultra-broadband IR spectroscopy end station for studying the ultrafast dynamics of strongly correlated materials, interstellar matter, energy materials, and photocatalytic reaction in solid, liquid, gas phases. For strongly correlated materials, some interesting issues and unclear mechanisms in perovskite-based solar materials, 2D materials, topological insulators, and superconductors will be revealed in this project. For interstellar matter, the real formation pathway of interstellar complex organic molecules and the identify of radicals and metastable-molecules which will be solved in this project. For energy materials and efficient catalysts, time-resolved operando spectroscopy will identify the intermediate state of molecule formed at the interface during CO2 reduction reaction. Furthermore, ultrafast phenomena are always keys to better understand the fundamentals of these materials. By using this advanced spectroscopic approach, the ultrafast physical and chemical reactions for converting or storing energy can be decoded.
