Abstract

Chalcostibite brick-like nanoparticles have been synthesized using hot-injection method in coordinating solvents. The CuSbS₂ nanobricks possess a band gap of 1.40 eV and the corresponding nanobrick-electrode shows an IPCE of 5%–15% in the visible region. Our work demonstrates CuSbS₂ nanobricks have potential in the field of solar energy conversion.
