摘要：

Cubic Cu2SnS3 and tetragonal Cu3SnS4 have been synthesized successfully using thiourea complexes of copper and tin in ethylene glycol by a simple change in the mode of mixing the reactants. While cubic Cu2SnS3 resulted from one-pot synthesis, mixing the colloids of copper and tin in ethylene glycol yielded tetragonal Cu3SnS4. The phases were characterized by high resolution powder x-ray diffraction (PXRD), UV-vis, Raman spectroscopy, SEM-EDX, HR-TEM and SAED measurements. Optical band gap of 0.92 eV (for Cu2SnS3) and 1.35 eV (for Cu3SnS4) were deduced from UV-vis spectroscopy data.
