Formation of metallic nanoclusters in silica by ion implantation

Study of Cu+, Ag+ and Au+ ion implantation into silicate glasses

“…Nowadays, it seems obvious that very good non-linear properties (considered as the χ3 coefficient measured by the Z-scan method) are revealed by the material having homogeneously distributed small-sized nanoparticles (approx. 5 to 20 nm, see [3,4,19,20]). …”

Nonlinear optical properties of MeV and keV ion beam synthesized Ag nanoclusters

“…The spectrum corresponding to the annealed sample (open circles) shows a surface plasmon resonance (SPR) peak around 400 nm, which is characteristic of the Ag nanoclusters in silica glass [1,9,10]. However no SPR peak is observed for the as-implanted sample (filled circles).…”

Optical Nonlinearities of Colloidal Metal Quantum Dot - Glass Composites for Nanophotonics

“…All the XRD peaks are identified as those of metallic tin crystallites and relative peak intensities confirm that there is no evidence of preferential orientation of the microcrystallites. [58]. Resonance enhancement of () 3 χ with in-diffusion of gold was exploited for high non-linearity at wavelength above 1000 nm [59].…”
