Abstract

Cu₃SbSe₃ nanocrystals have been synthesized using a hot-injection method. The Cu₃SbSe₃ nanocrystals possess a band gap of 1.31 eV and the corresponding nanocrystal-electrode shows an incident photon to current efficiency (IPCE) of 10–35% in the visible region. Our work demonstrates that Cu₃SbSe₃ nanocrystals have potential in photo-electric conversion device applications.
