Nanofluids of metal nanoparticles (NPs) have been studied for a long time, and the primary methods of their preparation involved wet chemistry. This work investigates the simultaneous production of Ag and Cu NPs by a physical method of magnetron sputtering using two gas aggregation cluster sources.
The NPs are subsequently deposited into a host liquid of polyethylene glycol to produce plasmonic nanofluids in which bands of localized surface plasmon resonance can be tuned by the Ag-to-Cu ratio.
