Abstract. On a basis of the comparative analysis of the references data the correlated dependencies between the optical characteristics of aqueous sols of spherical nanoparticles and their diameter have been discovered. As a result, the empirical dependencies between the values of the square of wave frequency in the adsorption maximum of the surface рlasmon resonance and average diameter of the nanoparticles were determined as well as between the values of the adsorption band width on a half of its height and silver nanoparticles distribution per size. Proposed dependencies are described by the linear equations with the correlation coefficients 0,97 and 0,84 correspondingly.
Key words: nanotechnology, silver nanoparticles, aqua sol, surface plasmon resonance, UV/Vis spectra.
