Abstract

Copper sulphide nanoparticles and nanorods were synthesised via a novel non-aqueous solvent method that employed ethanol as solvent and sodium dodecyl benzene sulphonate (SDBS) as a surfactant. The products were characterised by X-ray diffraction, transmission electron microscopy and UV-vis and photoluminescence spectroscopy. The results confirmed that ethanol was an excellent solvent and the concentration of SDBS was a vital factor in controlling the morphology of CuS. The potential formation mechanism for nanoparticles is proposed.
