“…Nobel metals such as gold and silver are amongst the most promising and most widely studied metallic nanoparticles in glass, while copper is sometimes included in extended studies [3]. In comparison with bulk metal, metallic nanoparticles embedded in an insulating matrix reveal a wide range of useful physical features and provide excellent prospects for significant technological applications such as nanoplasmonic devices [4], memory switching devices [5], electrical charge storage [6], light emission [7], optical non-locality [8], optical devices [9], and also a common colorant for glasses [10].…”

Nanoprecipitation in different oxide glasses by means of electron irradiation in transmission electron microscopy (TEM) has been compared in this study. Upon irradiation, groups or patterns of nanoparticles with various morphologies and sizes were formed in borosilicate glasses, loaded with zinc, copper, and silver. The study successfully includes loading ranges for the target metal from doping level (1%) over medium level (20%) to majority phase (60%). It is found that particle patterning resolution is affected by parallel processes of amorphous phase separation, glass ablation, and delocalised precipitation. In addition, via an in-situ study, it is confirmed that by heating alone without irradiation, no precipitate nanoparticles form.

“…AC NA plays a key role in sensing the toxic chemical like carcinogens and as an electrochemical sensor [34]. Bimetallic AC nano crystals, as a new class of materials, have great potential in optoelectronic devices for the non-linear optical properties due to their excitation of surface plasmon [35]. For the quantum confinement effect, AC NA finds use in the field of catalysis [36][37][38].…”

An Ag-Cu (AC) bimetallic alloy nanoparticles in various proportions were fabricated by facile electrochemical process is presented in this work. Apart from the electrochemical method of synthesis, the surface morphology, crystal structure and texture as well as the optical properties of the nano alloy have been investigated. The surface morphology and the particle size of the Ag-Cu deposits were deliberated by scanning electron microscopic studies. The preferred orientation and average particle size of the AC NTs were obtained by X-ray diffraction analysis. The well-dispersed AC nano alloy (NA) exhibited ultrafine size and high crystallinity corresponding to face centered cubic Ag and Cu. Ultraviolet-visible spectroscopy was performed to study the optical properties of the nano alloy and the results showed that the nano alloys have wide band gap energies 3.18, 3.57 and 3.03 eV for AgCu, AgCu 2 and AgCu 3 NAs, respectively. The studies on size, morphology and composition of the nanoparticles were performed by means of transmission electron microscopy, and energy dispersive X-ray Analysis.

“…[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.
