Abstract: The analysis of the optical properties of mechanochemically synthesized stannite Cu 2 FeSnS 4 nanocrystals has been performed using far-infrared spectroscopy. The Cu 2 FeSnS 4 stannite nanocrystals were synthesized mechanochemically from elemental precursors Cu, Fe, Sn, and S. Milling time was 45, 60, 90 and 120 min. Reflectivity spectra were analyzed using the classical form of the dielectric function, which includes the phonon and the free carrier contribution. The influence of milling time on synthesis of stannite Cu 2 FeSnS 4 is observed. Among the modes that are characteristic for the stannite Cu 2 FeSnS 4 , we registered the modes of binary phases of FeS and SnS. The total disappearance of the binary phases of FeS and SnS and forming pure Cu 2 FeSnS 4 is observed when the milling time is 120 min. Effective permittivity of Cu 2 FeSnS 4 and binary phases of FeS and SnS were modeled by Maxwell – Garnet approximation. [ABSTRACT FROM AUTHOR]
