Direct Evidence of Ultrafast Energy Delocalization Between Optically Hybridized J‐Aggregates in a Strongly Coupled Microcavity (Advanced Optical Materials 25/2024)

Résumé fourni par la source

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.
