Abstract

Great efforts have been devoted to the synthesis of various CsPbX3 nanostructures in view of their excellent photovoltaic performance and promising optoelectronic applications. However, the preparation of high-quality one-dimensional cesium lead halide nanotubes still remains challenging and unexplored. Here, we report a microwave-assisted synthetic approach for high-quality single crystalline CsPbI3 nanotubes featuring highly uniform sizes and stable and bright photoluminescence. Furthermore, a CsPbI3 nanotube based photodetector was assembled, which exhibits high sensitivity, stability and a fast response to 405 nm wavelength light. As a new member of the all-inorganic CsPbX3 nanostructure family, CsPbI3 nanotubes could provide a potential platform for understanding their fundamental properties and paving the way for their future application in optoelectronic devices.
