Abstract

Lead-halide perovskite are an interesting material platform for light-emitting devices but the underlying lasing mechanism is still disputed. Here, Schlaus et al. use time-resolved spectroscopy of CsPbBr3 nanowires to show that lasing results from stimulated emission of an electron-hole plasma.
