Cu3SnS4 (CTS) nanoparticles synthesis from cost effective metal precursor sources. |
| 초록 |
Copper tin sulfide (CTS) is an emerging candidate for solar application due to its favorable optical properties. Monodisperse Kuramite-Tetragonal Cu3SnS4 (CTS) nanoparticles are prepared by hot injection method involving cost effective sulfate metal precursor source. The crystal structure, size, atomic composition, oxidation state and optical characteristics of the nanoparticles are confirmed from X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS) and UV-visible spectroscopy, respectively. Hexagonal shaped particles within the size of 7-9 nm with an optimal band gap of 1.28 eV are obtained. XPS study shows that the Cu, Sn and S are in +1, +4 and -2 oxidation states, respectively. The plausible mechanism of the formation of CTS nanoparticles has been proposed. |
