摘要

Abstract

BSTRACTInorganic cesium lead halide perovskite nanowires (NWs) were synthesised by an in-plane self-assembly method. With the assistance of saturated solvent vapour

perovskite microparticles self-assembled into NWs. By stoichiometric adjustment of the halogen anion components in the NWs

their photoluminescence could be tuned to span the entire visible range. A detailed investigation of the lasing properties of the in-situ perovskite NWs and microplates revealed a lasing range of 420–560 nm

with typical thresholds of 18.8 μJ cm

−2

for CsPbBr

NWs and 8.87 μJ cm

for CsPbBr

microplates. The NWs exhibited robust stability under extended laser pumping in ambient atmosphere.
