Effect of Laser Parameters on the Characteristics and Stability of Ag NPs Produced by Laser Ablation in Stationary Conditions

The effect of laser ablation parameters on the size and stability of synthesized silver nanoparticles (Ag NPs) by laser ablation in deionised water was investigated. The results showed that the selected laser parameters (laser pulse wavelength and laser fluence) and ablation of the target in a fixed beam position had a direct effect on the size and size distribution of Ag NPs. The stability of all Ag nanoparticle samples prepared in different laser parameters has been studied. All the samples of Ag NPs presented remarkable long-term stability up to two months.
