The formation of binary alloy clusters in sequentially ion-implanted Au±Cu or Au±Ag silica glass has been studied as a function of the annealing atmosphere. Alloy formation has been evidenced in the as-implanted samples. The selective in ̄uence on Au precipitation of either oxygen or hydrogen annealing atmosphere governs the alloy cluster formation and the thermal stability.

Abstract
The formation of binary alloy clusters in sequentially ion-implanted Au±Cu or Au±Ag silica glass has been studied as a function of the annealing atmosphere. Alloy formation has been evidenced in the as-implanted samples. The selective in ̄uence on Au precipitation of either oxygen or hydrogen annealing atmosphere governs the alloy cluster formation and the thermal stability.File in questo prodotto:
