“…In the past few years, several research groups have studied the synthesis of nanometre-sized particles of noble metals embedded especially in silica glass, occasionally in soda-lime silicate glasses [9][10][11]. Besides noble metal implantation (Cu, Ag, and Au), sequential ion implantation of two metal species (see [5,12,13]) or co-implantation of noble metal, an oxidising or reducing ion (atom) [14][15][16] has been done to form alloy metal nanoclusters and thus influence the resulting non-linear properties.…”

“…Standing apart from the rest, the ion implantation technique enables us to introduce high concentrations as well as different metals into the near surface regions of the dielectric layers. [4][5][6] The formation of NPs by the ion implantation technique in the layer depends on its own properties, as well as on the ion implantation parameters (ion dose and energy, target and annealing temperature, etc.). 7 Generally, the depth distribution of implanted ions and their penetration in the layer-target are studied by various physical profiling techniques like Rutherford Backscattering Spectroscopy (RBS) or Secondary Ion Mass Spectroscopy (SIMS) and by computer simulation such as SRIM.…”

We report an uncommon study of the insertion of distributions of both volume fraction and depolarization factors in the modeling of the plasmonic properties of implanted Ag nanoparticles (Ag-NPs) in a SiO2 layer when using spectroscopic ellipsometry (SE) characterization. The Ag-NPs were embedded in the SiO2 matrix by Ag+ ion implantation at various doses of 0.5 × 1016, 1 × 1016, 2 × 1016, and 5 × 1016 ions cm−2. The formation of the Ag-NPs in a host matrix of SiO2 was controlled by transmission electron microscopy (TEM). The Ag-NPs are self-organized in the layer, and their mean radius ranges between 2 and 20 nm. The optical properties of layers were extracted by modeling the SE parameters by taking into account the depth profile concentration of Ag-NPs. The mixture of SiO2 and Ag-NP inclusions was modeled as an effective medium according to the shape distributed effective medium theory (SDEMT). In addition to the optical responses, it is shown that this model enables the explanation of the impact of NP shape distribution on the plasmon band and provides precious information about the NP shape characteristics. A good agreement was obtained between ellipsometry and TEM results. The distribution of the volume fraction in the film was found to lead to a gradient of effective dielectric function which was determined by the SDEMT model. The effective dielectric function reveals distinct Ag plasmon resonance varying as the Ag+ ions dose is varied. The real part of the dielectric function shows a significant variation around the plasmon resonance in accordance with the Kramers-Kronig equations. All determined optical parameters by SDEMT are provided and discussed. We highlight that SE combined with SDEMT calculations can be considered as a reliable tool for the determination of the NP shape and volume fraction distributions without the need of TEM.

“…[2] Formation of bimetallic composites should broaden the spectral range where the nanocomposites can be used. Till now, there are only few works regarding bimetallic composites, [3][4][5][6] and both the mechanism of their formation and structure are poorly understood. Here, we present studies of the formation and optical properties of copper-silver glass-metal nanocomposites.…”

The studies of bimetallic nanocomposites made in glass by metal ion exchange process and heat treatment in hydrogen atmosphere are presented. The distributions of silver and copper nanoparticles in glass are obtained using secondary ion mass spectrometry measurements and optical absorption spectroscopy. It was shown that in bimetallic nanocomposites containing silver and copper inclusions, copper nanoparticles are closer to the surface than silver ones, and quasi-layered structure of copper nanoparticles can be formed.
