Summary: | Inorganic 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 CsPbBr3 NWs and 8.87 μJ cm−2 for CsPbBrxCl3-x microplates. The NWs exhibited robust stability under extended laser pumping in ambient atmosphere. |
