Orthorhombic phase Bi2S3 micro/nanocrystals with various morphologies have been successfully synthesized via a facile one-step hydrothermal approach without any templates or surfactants. The formation mechanisms of the Bi2S3 micro/nanocrystals have been proposed on the basis of the experimental results. The photoresponse properties using Bi2S3 nanorods as a representative system show a significantly enhanced conductivity and a steady photoresponse with a fast response time of 177.1 ms, indicating its potential application in high-speed and high-sensitivity photodetectors and photoelectronic switches.
