Abstract

The fabrication of a photodetector and gas sensor based on hierarchical Bi₂S₃ nanostructures is reported. Single crystalline Bi₂S₃ nanostructures with [001] growth direction were obtained via a facile hydrothermal method without any templates or surfactants. The photodetector showed steady photoresponses with a fast response time of ∼50 ms. Moreover, these Bi₂S₃ nanostructures exhibited a good sensing to methanol. These results show these hierarchical Bi₂S₃ nanostructures are promising candidates for constructing optoelectronic and gas sensing devices.
