Abstract

Ag+ was implanted in silica glass and beta alumina crystal and studied using particle backscattering and optical absorption. We found that Ag aggregates into colloidal metallic particles and when annealed diffuses toward the surface. The activation energy for diffusion is 0.14 eV in silica glass and 0.16 eV in beta alumina. Computer simulations indicate fast Ag+ diffusion is due to large concentrations of vacancies deposited along the track of the implanted ion. The high ionic conductivity of beta alumina promotes uniform spreading of the implanted layer.
