Scaling Law for Kasha’s Rule in Photoexcited Molecular Aggregates
Scaling Law for Kasha’s Rule in Photoexcited Molecular Aggregates
We study the photophysics of molecular aggregates from a quantum optics perspective, with emphasis on deriving scaling laws for the fast nonradiative relaxation of collective electronic excitations, referred to as Kasha's rule. Aggregates exhibit an energetically broad manifold of collective states with delocalized electronic excitations originating from near-field dipole–dipole exchanges …
