Single-step synthesis of gold-silver alloy nanoparticles in ionic liquids by a sputter deposition technique.
The simultaneous sputter deposition of gold and silver onto ionic liquids formed bimetallic alloy nanoparticles, which exhibited composition-sensitive surface plasmon resonance, the peak wavelength being red-shifted with an increase in the surface area of the gold foil targets sputtered.
