Au, Ag and Au:Ag colloidal nanoparticles synthesized by pulsed laser ablation as SERS substrates
Chemically pure colloidal suspensions of gold and silver nanoparticles were synthesized using pulsed laser ablation. The dependence of laser fluence on the surface plasmon characteristics of the nanoparticles was investigated. Au:Ag colloidal suspensions were prepared by mixing highly monodisperse A...
