A cation exchange reaction of wide‐band‐gap crystalline ZnS with CuCl 2 and SnCl 4 in triethylene glycol was developed to synthesize nonstoichiometric Cu 2 ZnSnS 4 with crystallite size more than 100 nm. The materials were characterized by powder X‐ray diffraction, electron microscopy, Raman, and energy dispersive X‐ray elemental mapping. The method allows the formation of Zn‐rich phases and good control of the crystal size and shape. No narrow‐band‐gap highly conductive Cu x S impurities were observed.
