基于光与物质强耦合条件下的非辐射能量转移特性的研究

Studies on non-radiative energy transfer under light-matter strong coupling interaction are important to understand the novel physical and chemical properties of the materials which show great potential for application in many fields. It can break the strict requirements of the traditional donor-acceptor system and achieve the ultra-distance and ultrafast energy transfer. However, the physical mechanism of this phenomenon is not clear. Here, this project will mainly focus on the physics and application of the energy transfer via light-matter strong coupling based on the experiment and the theory: To build and develop several donor-acceptor systems under light-matter strong coupling hybrid state which will be excepted to get an in-depth understanding of the polariton contribution on non-radiative energy transfer. By adjusting the different donor-acceptor distances and the different strong coupling strengths, to further study on the relation between these parameters and the energy transfer efficiency, in order to establish and optimize the energy transfer model. By using of the composite system, to explore the difference and the relationship between the strong coupling energy transfer and the traditional way. The applicant published 38 SCI papers related to this project including 10 first author papers, which have been cited for more than 500 times. Two of these papers published in Angew. Chem. Int. Ed. were highlighted by Science in a full-page comment. These research results establish solid theoretical and experimental basis for further exploration.
