Colloidal synthesis and characterizations of wittichenite copper bismuth sulphide nanocrystals.
Wittichenite (Cu(3)BiS(3)) nanocrystals have been synthesized utilizing a hot-injection method. They have been characterized in detail. Cu(3)BiS(3) 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 Cu(3)BiS(3) nanocrystals have potential in the application of solar cells.
