Electron microscope study of silver colloids in KCl : Ag

摘要

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.
