Copper sulphide nanoparticles were synthesized by reacting a copper-ammonia complex with thiourea in aqueous micellar solutions of cationic, non-ionic and anionic surfactants. A blue shift in the absorption spectra revealed the formation of size-quantized nanoparticles. The influence of micelles in mediating the stabilization was studied by carrying out the reactions in surfactant solutions above and below the critical micelle concentration. The effect of thiourea on the stability of the nanoparticles was studied by synthesizing the nanoparticles at different mole ratios of reactants. Characterization of the nanoparticles was achieved by the use of transmission electron microscopy (TEM), X-ray powder diffraction (XRD), energy dispersive X-ray microanalysis (EDAX) and UV–vis spectroscopy.
