Copper sulfide nanoparticles with a grain dimension between 10nm and 50nm were obtained by a simple chemical process in the first step. The reaction of thiourea with different sources of copper in distilled water, and by adjusting the proportion of reactants was studied. The synthesis of the nanoparticles was made by simple modified hydrothermal route at 90°C for 2 hour followed by annealing at 500°C...
