TL;DR: The controlled growth of in-plane directional perovskite CsPbBr3 NWs are demonstrated, induced by graphoepitaxial effect on annealed M-plane sapphire substrates, which will provide promising opportunities in constructing integrated nanophotonic and optoelectronic systems.

TL;DR: High-quality all-inorganic cesium lead halide alloy perovskite micro/nanorods with complete composition tuning by vapor-phase deposition are reported and function as effective Fabry-Perot cavities for nanoscale lasers.

TL;DR: This work illustrates that the well-controlled synthesis of metal cesium lead halide perovskite nano/microspheres may offer an alternative route to produce a widely tunable and greatly miniaturized single-mode laser.

TL;DR: Time-resolved photoluminescence, transient reflection spectroscopy, and electrical transport measurements show that the CsPbBr3 epitaxial thin film has a slow charge carrier recombination rate, low surface recombination velocity, and low defect density of 1012 cm-3, which are comparable to those of cesium lead bromide perovskite single crystals.

TL;DR: Fundamental insights for the practical applications of all-inorganic perovskite CsPbX3 nanowires in designing light-emitting devices and integrated nanophotonic systems are provided.
