摘要

A method is proposed for diagnostics of parameters of optically transparent ultrafine media containing particles of noble metals (Au, Ag). In accordance with this method, parameters of small-sized gold and silver particles (their effective diameter, concentration, and size-distribution dispersion) in optically transparent condensed media were investigated using, in combination, the methods of laser probing and two-factor analysis of the surface-plasmon resonance band on the basis of simulation of the dimension and spectral dependences of the efficiency of extinction and scattering of radiation by this medium in accordance with the Mie theory.
