Over the last decade halide perovskite microwires have emerged as a platform for numerous photonic and optoelectronic applications including solar cells, lasers, optical gas sensors, photodetectors, electroluminescent photodetectors, integrated photonic devices, etc. [1-6] Colloidal synthesis of microwires have many advantages over frequently employed chemical vapor deposition (CVD) and substrate-assisted solution growth. Among them there are easy doping of perovskite crystal lattice by transition metal ions that results in bandgap tuning and change in conductivity, along with simplicity of microwires integration with various nanostructures and electrodes by using drop-casting to produce complex devices. However, there is the only report devoted to colloidal perovskite microwires so far [7]. In my talk, I will present a novel colloidal synthesis of all-inorganic perovskite microwires, laser action in them, as well as optoelectronic devices, in particular single-crystal-based gas sensor and memristor.
