Drastic transitions of excited state and coupling regime in all-inorganic perovskite microcavities characterized by exciton/plasmon hybrid natures
文献摘要：
Lead-halide perovskites are highly promising for various optoelectronic applications,including laser devices.However,fundamental photophysics explaining the coherent-light emission from this material system is so intricate and often the subject of debate.Here,we systematically investigate photoluminescence properties of all-inorganic perovskite microcavity at room temperature and discuss the excited state and the light-matter coupling regime depending on excitation density.Angle-resolved photoluminescence clearly exhibits that the microcavity system shows a transition from weak coupling regime to strong coupling regime,revealing the increase in correlated electron-hole pairs.With pumping fluence above the threshold,the photoluminescence signal shows a lasing behavior with bosonic condensation characteristics,accompanied by long-range phase coherence.The excitation density required for the lasing behavior,however,is found to exceed the Mott density,excluding the exciton as the excited state.These results demonstrate that the polaritonic Bardeen-Cooper-Schrieffer state originates the strong coupling formation and the lasing behavior.
