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

for CsPbBr

NWs and 8.87 μJ cm

for CsPbBr

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