Abstract
Ablation of Au and Ag targets in water by a Cu vapor laser generates Au and Ag sols. The metal nanoparticles obtained after evaporation are disk-shape d (diameter in the 20-60 nm range, thickness of few nanometers). Their form ation is observed at laser fluence between 10 and 20 J/cm(2). Both aqueous sols are characterized by well-resolved plasmon bands around 400 run (Ag) a nd 520 mn (Au.).
