The Role of U.V. Light in the Inhibition of Electroless Deposition

Abstract
Ultraviolet light has been shown to be effective in inhibiting the electroless deposition of Cu, Ni, and Co if applied after sensitization, and of Ni and Co after activation. Electron microscopic techniques are applied to investigate these phenomena. It is concluded that structural changes in the sensitizing and activating agents induced by the u.v. light are connected with the inhibition of metal deposition.
