Silver nanoparticles were synthesized by pulsed laser ablation (Q-switched Nd:YAG, ë=1064nm, 10 ns pulse duration and E=100-900 mJ) of pure Ag metal plate immersed in double distilled and deionised water DDDW. Spectral measurements, such as surface plasmon extinction SPE spectra of the produced nanoparticles solution were measured. The size and concentrations measurements of produced nanoparticles were estimated. UV-VIS absorption spectra of produced solution show a sharp peak around 400 nm, indicating the produced Ag nanoparticles with a narrow size ranging from 5 to 50 nm with almost spherical shape.
