英文摘要	Lead-free zero-dimensional (0d) organic-inorganic metal halide perovskites have recently attracted increasing attention for their excellent photoluminescence properties and chemical stability. here, we report the synthesis and characterization of an air-stable 0d mixed metal halide perovskite (c8nh12)(4)bi0.57sb0.43br7.h2o, in which individual [bibr6](3-) and [sbbr6](3-) octahedral units are completely isolated and surrounded by the large organic cation c8h12n+. upon photoexcitation, the bulk crystals exhibit ultra-broadband emission ranging from 400 to 850 nm, which originates from both free excitons and self-trapped excitons. this is the first example of 0d perovskites with broadband emission spanning the entire visible spectrum. in addition, (c8nh12)(4)bi0.57sb0.43br7.h2o exhibits excellent humidity and light stability. these findings present a new direction towards the design of environmentally-friendly, high-performance 0d perovskite light emitters.
