Electron microscope study of silver colloids in KCl : Ag

Abstract

Transmission electron microscope studies of the colloids of silver in KCl : Ag crystals show that the colloidal particles are spherical in shape and have a size distribution among them. Using the observed size distribution and modified optical constants for small metal particles by the Kawabata-Kubo method and Mie's theory, the calculated shapes of the optical bands agree well with the observed band shape.
