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. Long-lived polariton: In organic cavities, the hybrid light-matter states display intricate dynamics due to the molecular nature of such systems. The authors investigate these dynamics and find that the polariton is surprisingly long-lived.
