摘要：

Silver nanoparticles (NPs) were synthesized by laser (Nd:YAG, 1064nm) ablation of a silver target in various concentrations of NaCl solutions as well as in distilled water. The optical properties, size distribution, and agglomeration of NPs were investigated by several diagnostics. The UV-Vis-NIR absorption spectrum of the Ag NPs exhibits absorptions in the ultraviolet and visible regions because of interband transition and surface plasmon resonance oscillations of Ag NPs, respectively. The average size of produced particles is increased as concentrations of NaCl in the solutions increases. TEM and SEM micrographs were used to study the size distribution and morphology of NPs. TEM images indicate that the aggregation of NPs in NaCl solutions is more than distilled water.
