Polariton dynamics under strong light–molecule coupling
ChemPhysChem, 2013•Wiley Online Library
We present a comprehensive experimental study of the photophysical properties of a
molecule–cavity system under strong coupling conditions, using steady‐state and
femtosecond time‐resolved emission and absorption techniques to selectively excite the
lower and upper polaritons as well as the reservoir of uncoupled molecules. Our results
demonstrate the complex decay routes in such hybrid systems and that, contrary to
expectations, the lower polariton is intrinsically long‐lived.
