Abstract
Metal-halide perovskites (MHPs) with unique electronic and optical properties have emerged as promising materials with a broad spectrum of applications in photovoltaics, optoelectronic, and photonic devices. The distinct properties and tremendous potential of MHPs are intricately defined by excitons and collective quantum states. This article reviews the excitonic states and coordinated interplay of charge, spin, and lattice. We discuss the recent experimental and theoretical discoveries of excitonic phenomena, as well as correlated states involving condensation and cooperative emission. Additionally, our exploration extends to the structural properties of MHPs that facilitate the emergence of robust quantum states, even at room temperatures. Finally, an overview of the remaining challenges and potential applications of MHPs in quantum optics, coherent light sources, electrically driven amplified spontaneous emission, and superfluorescent lasing is provided.
期刊介绍：
MRS Bulletin is one of the most widely recognized and highly respected publications in advanced materials research. Each month, the Bulletin provides a comprehensive overview of a specific materials theme, along with industry and policy developments, and MRS and materials-community news and events. Written by leading experts, the overview articles are useful references for specialists, but are also presented at a level understandable to a broad scientific audience.
