Abstract

The effect of the change in concentration of electrolyte solutions on the optical properties of nanoparticles of cadmium sulfide formed in a polymeric matrix volume by the method of layered chemisorptions of ions is considered. It is shown, that with increase in concentration of cadmium ions in a solution at equal quantity of the cycles the band gap of nanoparticles decreases. It is explained by that with an increase in concentration of cadmium ions in electrolyte solutions the degree of filling adsorption centers increases. This leads to the decrease in distance between the particles, and promotes the acceleration of the coalescent process of nanoparticles in polymeric matrix volume..
