Background/Objectives: Methods for the synthesis of Ag-Au alloy nanoparticles have received considerable attention due to their special characteristics and applications. Among different synthesis methods for alloy nanoparticles, high-voltage wire explosion of twisted wires has significant advantages for manufacturing production. Method/Statistical Analysis: In this work, Ag-Aualloy nanoparticles were synthesized by a high-voltage electrical explosion of twisted wires (of Ag and Au) in deionized water for the first time. The compositions of obtained nanoparticles were changed by adjusting the cross-section ratio of Ag and Au twisted wires. Finding: The obtained nanoparticles were characterized by applying X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS) techniques. Localized surface plasmons resonance (LSPR) of Ag-Au alloy nanoparticles were studied by UV-vis spectroscopy and it was found that the position of the LSPR band of the nanoparticles could be tuned by the variation of their composition linearly. Conclusion/Application: Among different synthesis methods, high-voltage EEW has higher efficiency in industrial production of metallic nanoparticles, and using twisted wires in this method is a good substitution of pre-Alloyed and electrodeposited wires for fabrication of alloy nanoparticles.
