    Abstract: 本計畫主要目的為建立一新穎的飛秒級時間解析紅外光譜量測實驗站以研究各 式強關聯材料、星際物質、新興能源材料及催化反應在固態、液態、氣態下的超 快動力學。在強關聯材料方面,例如:太陽能鈣鈦礦材料、二維材料、拓樸絕緣 體、超導體等都是值得利用此新穎光譜技術深入研究的對象,以協助我們了解許 多重要且尚未釐清的機制及物理課題。在星際物質方面,有待此新穎超快光譜量 測技術協助了解星際複雜有機分子的生成過程,以及自由基與中間產物的判定。 在新興能源材料及催化反應方面,具時間解析的原位光譜提供二氧化碳電還原過 程中表面分子催化中間態,亦可研究材料在進行轉能或儲能時之物理及化學反應 之超快現象,有利於詳盡反應機制之探討。 ;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.
