Production of Silver Nanoparticles by 532 nm Pulsed Laser Ablation in NaCl

In this experimental research silver nanoparticles are produced in NaCl solution by laser ablation method.Our aim was investigating the effect of NaCl amount in the ablation medium on the characteristics of nanoparticles. A7- ns pulsed Neodymium YAG laser (Nd:YAG) at 5 J/cm2 fluence and 532 nm wavelength was employed to produce Ag nanoparticles in distilled water and distilled water with 3 different concentrations of NaCl. The optical properties, size distribution and agglomeration of nanoparticles were investigated by several diagnostics. UV-Vis-NIR absorption spectrum of samples showed the surface plasmon resonance absorption of nanoparticles at about 400 nm- Transmission electron microscopy (TEM) were used to study the size distribution and morphology of nanoparticles. Dynamic light scattering (DLS) was employed to measure the hydrodynamic size of nanoparticles in suspensions. With XRD pattern the lattice structure of nanoparticles were studied.
