Dimensional dependencies of optical parameters of nanodimensional metal particles

The results of researches of the investigations of dimensional dependencies of optical parameters of nanodimensional particles of silver, nickel chrome in high-frequency spectral diapason 1.1+3.2 eV are presented. It is shown, that values of high-frequency conductivity of nanodimensional particles of these metals are considerable lesser than in macroscopic samples and with diminishing of particle dimensions the values of high-frequency conductivity diminish by 1-2 orders. Determined is the connection of dimensional changes of high-frequency conductivity of nanoparticles with their specific absorption.
