摘要：

Femtosecond laser ablation of silver plate placed in water is used to produce nanoparticle suspension. The method is easy to operate and the suspension is relatively stable. The optical properties and the size distribution of the suspension are studied with UV-vis absorption spectroscopy and dynamic light scattering, respectively. The shape of the nanoparticles is investigated by anatomic force microscope, which is near spherical. There are two kinds of nanoparticles, small particles with diameter about 35nm, and large particles with diameter about 120nm
