Nanocluster formation in silicate glasses by sequential ion implantation procedures

Cluster formation is studied after sequential double implantation (Cu, Ni; Ag, S) in silica and soda-lime glass. The structure and properties of nanocluster composites are investigated by optical absorption spectroscopy and transmission electron microscopy, evidencing the formation of core-shell structures. The presence of metal alloy clusters is also investigated by means of synchrotron-radiation-based techniques.
