Precursor driven one pot synthesis of wurtzite and chalcopyrite CuFeS2

A facile precursor dependent single step, one pot solution based synthesis of wurtzite and chalcopyrite polymorphs of CuFeS2 has been developed by reacting a Cu(I) thiourea complex with Fe2(SO4)3 and FeCl3 separately in ethylene glycol. The phases have been characterized by structural refinements, SEM-EDX, TEM-SAED, Raman, UV-Visible spectroscopy and TGA measurements.
