Characterization of Ag and Au nanoparticles created by nanosecond pulsed laser ablation in double distilled water

▶ Chemical-free Ag and Au nanoparticles were produced by nanosecond laser ablation. ▶ The ablation process has been performed by Nd:YAG laser in double distilled water. ▶ As-prepared samples have been investigated by TEM and UV-VIS transmission. ▶ The laser fluence at 1064 nm does not influence the average particle size. ▶ The mean size increases with the increasing of the laser fluence at the SHG.
