Abstract

Direct Evidence of Ultrafast Energy Delocalization

Energy delocalization is observed in a strongly coupled cavity containing two layers of donor and acceptor molecules, separated by an inert spacer layer of 2 μm thickness. Margherita Maiuri, Tersilla Virgili, and co-workers (see article number 2400821) use two-dimensional electronic spectroscopy, a technique that provides simultaneously high spectral and temporal resolution, to probe the dynamics of the energy flow processes following ultra-fast excitation. Their finding opens new perspectives on remote photo/induced energy transport useful in advanced optoelectronic devices.

强耦合微腔中光学杂化 J 聚体间超快能量析出的直接证据（先进光学材料 25/2024）

在一个包含两层供体分子和受体分子的强耦合空腔中观察到了能量脱ocalization现象，这两层分子被厚度为 2 μm 的惰性间隔层隔开。Margherita Maiuri、Tersilla Virgili 及其合作者（见文章编号 2400821）使用二维电子光谱技术（一种同时提供高光谱分辨率和时间分辨率的技术）探测了超快激发后能量流动过程的动态。他们的发现为先进光电设备中的远程光/诱导能量传输开辟了新的前景。
