Abstract
The clustering process of gold atoms in ion-implanted silica, during annealing in different atmospheres, is experimentally investigated and phenomenologically described. With respect to inert (Ar) or reducing atmosphere, annealing in oxidizing (air) atmosphere is the most effective in promoting cluster formation above due to a thermally activated correlated diffusion of gold atoms and excess oxygen molecules coming from the atmosphere.
