<p>In this work, quaternary chalcogenite Cu2FexSn1-xS3 (CFTS) flower-like nanostructures (where x=0,0.6,1) have been successfully synthesized by solvothermal approach. The nanocrystals were characterized by means of X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM),Raman Scattering spectroscopy, and UV-Vis-NIR absorption spectroscopy. The nanocrystals sizes are calculated by Deby Sherrer formula to be S1(x=0) 10.71nm, S2(x=0) 8.15 nm and S3(x=1) 22 nm. UV-Vis absorption spectra of as-synthesized CFTS crystals dispersed in ethanol showed the increasing of absorption in visible region of light. The band gap energies of samples were: 1.06 eV for S1 (x=0), 1.37 eV for S2 (x=0.6) and 1.61 eV for S3 (x=1) respectively. As can be seen the optical band gap of samples increases from 1.06 to 1.61 eV by increasing of Fe dopant.</p>
