Abstract: (653 Views)
This paper discusses the results of synthesizing Ag-Au alloy nanoparticles (NPs) using a nanosecond pulsed laser. In this study, the colloidal Ag and Au NPs were separately prepared by nanosecond pulsed laser ablation in distilled water. An appropriate mixed sample of these colloidal NPs was post-irradiated under a uniform external electric field (EEF), resulting in Ag-Au alloy formation. The synthesized colloidal alloy NPs were characterized using scanning electron microscopy (SEM) and UV-vis absorption spectroscopy. The results indicated that the EEF could significantly reduce the Ag-Au alloy formation time. The results also showed that the localized surface plasmon resonance wavelength of the NPs synthesized under a uniform external electric field was less than those NPs produced apart from the field.
