Synthesis of silver nanoparticles by Nd:YAG laser and study Optical Limiting Behavior of colloid

Raad Sh. Alnayli, Hanan Alkazaali


In the present work, silver nanoparticle was synthesis by pulse laser ablation by using (Q-switched Nd:YAG) pulse duration10ns and (E=80mJ, λ=532nm) of silver metal target in deionize-water and ethanol. The results of XRD explain that not found any impurity in diffraction peaks in the pattern and Ag nanoparticles have high quality from of crystalline, which evidences the presence of silver particles with FCC structure. The optical properties were studied with Ultraviolet- Visible (UV-Vis) spectrophotometer which showed blue-shaft with pulse number, and atomic force microscope (AFM) indicates the size in nanometer (nm) range abut(40-80)nm.
