Lead-halide perovskites are generally excellent light emitters and can have larger exciton binding energies than thermal energy at room temperature, exhibiting great promise for room-temperature exciton-polaritonics. Rapid progress has been made recently, although challenges and mysteries remain in lead-halide perovskite semiconductors to push polaritons to room-temperature operation. In this Perspective, we discuss fundamental aspects of perovskite semiconductors for exciton-polaritons and review the recent rapid experimental advances using lead-halide perovskites for room-temperature polaritonics, including the experimental realization of strong light–matter interaction using various types of microcavities as well as reaching the polariton condensation regime in planar microcavities and lattices.

用于室温激子极化激子的钙钛矿半导体

卤化铅钙钛矿通常是极好的发光体,并且在室温下可以具有比热能更大的激子结合能,显示出室温激子极化的巨大前景。尽管在卤化铅钙钛矿半导体中将极化子推向室温运行仍存在挑战和谜团,但最近取得了快速进展。在这个观点中,我们讨论了用于激子极化的钙钛矿半导体的基本方面,并回顾了最近使用卤化铅钙钛矿进行室温极化的快速实验进展,包括使用各种类型的微腔实现强光-物质相互作用的实验在平面微腔和晶格中达到极化子凝聚状态。
