Abstract
A stable colloidal dispersion of (CuS) nanoparticles in water has been prepared by employing copper acetate monohydrate and thiourea as starting materials in the presence of SDS, PVP and Na-AOT as stabilizing agents. UV–visible spectrophotometer, X-ray powder diffraction and transmission electron microscopy (TEM) are used to characterize the nanoparticles. The average diameter of the particles is ∼76 nm. The influence of thiourea concentration on conversion of golden brown copper sulfide sol to green form is also studied. The factors affecting the stability of the dispersion have also been investigated.
