In this study, we fabricated microcavity with BP1T-CN organic single crystal as the active layer and measured time-resolved fluorescence characteristics to consider relaxation processes of exciton and polariton states. From the experimental results, it was shown that the lifetime of the reservoir excitons could be reduced by the introduction of the resonator structure, and that the mode could have different relaxation paths.
