△ [19a-Z06-1] Time-resolved spectroscopy of relaxation dynamics in an organic semiconductor (TDAF) microcavity exciton-polariton system
Keywords:Exciton-polariton, Microcavity, Organic semiconductor
In this study, we performed time-resolved transient absorption spectrum measurements using a femtosecond pulsed laser for the excitation energy relaxation process in the organic semiconductor exciton polariton, which is a type of elementary excited state of substances that interact with light. We try to consider the formation process of the polariton condensed state observed at the excitation intensity above the threshold value from the viewpoint of energy relaxation.
