| dc.description.abstract | CuIrSnS4, CuIrSnSe4 and CuIrSnS2Se2 were synthetized by a solid-state reaction at 700 °C. Powder X-ray diffraction patterns were consistent with normal spinel-type structure. Scanning electron microscopy (SEM-EDS) images showed a uniform distribution of Cu- Ir-Sn-S and Se atoms in the samples. Raman scattering analysis revealed A1g, Eg, and three F2g vibrational modes in spectra (cubic Fd3m space-group). Signal at ~320 cm-1 corresponded to the A1g mode, while the band at 230 cm-1 was assigned to the F2g(2) mode due to the asymmetric stretching of the Cu-X bond. Raman spectra were compared with those of the previously published thio- and selenospinels. | es_CL |
