ABSTRACT
In material physics and chemistry preparation of nanosized particles, an artificially engineered new structure with new properties is a major goal. This chapter discusses formation of monolayers made of silver sulfide particles organized in a hexagonal network on a long-distance range without any external forces. Syntheses performed in oil-in-water micellar solutions induce a control in the shape and the size of copper metallic particles. In reverse micelles, the size of copper metallic particles is controlled by the water content. The silver sulfide nanosize particles synthesized in reverse micelles are coated by dodecanethiol and dispersed in heptane. The change in size and in the shape has been performed either in water-in-oil or oil-in-water colloidal solution. From absorption spectroscopy it has been demonstrated that colloidal copper particles are characterized by a plasmon peak. In oil-in-water micelles, copper dodecyl sulfate, Cu(DS)2 is used as the reactant.
