Wittichenite (Cu3BiS3) nanocrystals have been synthesized utilizing a hot-injection method. They have been characterized in detail. Cu3BiS3 nanocrystals possessed a band gap of 1.56 eV, and the corresponding nanocrystal-film shows a clear photoresponse in I-V measurements. Our work illustrates that Cu3BiS3 nanocrystals have potential in the application of solar cells.
