Optical Properties Research of Cadmium Sulphide Nanoparticles Received by the Interaction of the Reverse Emulsions Based on Sodium bis(2-ethilhexyl) Sulfosuccinate

By the inverted emulsions the sodium bis(2-ethilhexyl) sulfosuccinate, containing solutions of sodium sulfide and cadmium chloride, cadmium sulfide nanoparticles were synthesized. Based on UV-ranges of a transmission the band gap and the CdS particles’ sizes were determined. Two groups of particles’ depressiveness were identified. It is established that the order of the reversed emulsions coacervating with reagents changes the arrangement and properties of the formed colloidal particles. By the reverse emulsion coacervating with CdCl2 solution to emulsion with Na2S solution beside sulfide cadmium particles S8 molecules are formed. These molecules restrained CdS particles growth.
