摘要: Exciton–polaritons in semiconductors are quasi-particles which have recently shown the capability to undergo phase transition into a coherent hybrid state of light and matter. The observation such organic microcavities has attracted increasing attention for their characteristic reaching condensation at room temperature. In this work, emission properties polaritons demonstrated not depend on overlap between absorption states molecule that dynamics modifi ed strong coupling regime, showing signifi cant enhancement photoluminescence intensity as compared bare dye. This paves way investigation molecules with large coeffi cients but poor effi ciencies realization polariton condensates electrically injected lasers by exploiting exciton-photon regimes.
