Abstract We have demonstrated a flexible method for preparing Cu 2 ZnSnS 4 (CZTS) nanocrystals by use of zinc ethylxanthate (Zn(ex) 2 ) and copper ethylxanthate (Cu(ex) 2 ). TEM, SEM, XRD, UV–vis, EDS, XPS and TG‐DTA indicate that the CZTS nanocrystals have been successfully synthesized. As air‐stable molecular precursors, Zn(ex) 2 and Cu(ex) 2 can optimize the synthesis of quaternary CZTS nanocrystals because Cu(ex) 2 and Zn(ex) 2 facilitate the formation of homogeneous precursor solutions including all precursors and then for the flexible production of CZTS nanocrystals in homogeneous reaction solutions.
