Abstract:

A series of high purity silica samples were sequentially implanted with Ag and Cu ions at energies such that the depth distributions for each of the ions overlapped. The samples were characterized by RBS, TEM and optical spectroscopy. The optical response was found to be dependent on the order of sequential implantation, as well as the relative concentration of the implanted elements. The changes in the optical response are attributed to composition changes of the metal colloids that are formed as a result of alloying of the sequentially implanted metal ions, as well as to changes in the size the colloids.
