| Popis: | In this paper, we introduce a new technique for the synthesis of mohite copper tin sulphide (Cu2SnS3) nanoparticles. The method employed is cost effective, non-vacuum, room temperature colloidal synthesis. Here two sulphur sources are used in the synthesis process, sodium sulphide and thioacetamide where the latter is assumed responsible for the mohite crystal structure. The as-prepared sample was characterized using XRD, Laser Raman Spectrometer, SEM/EDS, UV–VIS-NIR spectrophotometer and FTIR spectrophotometer. The sample synthesized appears greenish-black with a metallic lustre. Due to the presence of free electrons on the nanoparticle surface, surface plasmon resonance occurs at 807 nm. Using the uncertainty principle, the plasmon lifetime has been calculated to be 42.5 ns, which is a reasonably longer lifetime, enabling higher photon absorption. Thus mohite copper tin sulphide nanoparticles have a potential application in the absorber layer of low cost plasmonic solar cells. |
