Effect of water pressure on the size of nanoparticles in liquid-phase laser ablation

摘要

In this work, we studied the effect of applying external pressure to ambient water in liquid-phase laser ablation on the size of nanoparticles using a laser light scattering technique. We observed analogous behaviors for the temporal variations of the total intensities of the scattered laser light at different water pressures. The theory of Rayleigh-Mie scattering suggests that the size of nanoparticles decreases with the water pressure.
