Abstract: (401 Views)
In this paper the growth of nano-particles in laser ablation within a liquid by Orbital Motion Limited mechanism (OML) is simulated. It is assumed that the expanding plasma of the ablation has a supersonic speed up to 8000 m/s. Calculation results show that such a drift motion will cause the nano-particles to lose their symmetric spherical shapes and get a pine-like shape. It is concluded that if the growth of nano-particles obeys the electrical charging theorem then the shape of the produced nano-particles in real experiments should not be spherical but must be pine-like instead. As such thing has not been seen in the synthesized nano-particles from the experimental liquid-phase ablation; it seems that the OML theorem for nono-particle growth is rather doubted.
