Abstract

Pulsed laser ablation of Au target in n-alkanes generates Au sols.
Experiments have been performed using the second harmonic of a Nd:yttritium-aluminum-garnet
at 532 nm wavelength with a 5 ns pulse duration at a repetition rate
of 10 Hz and fluences ranging from 1 to 200 J/cm(2). Data coming
from optical extinction show that the length of the hydrocarbon chain
is able to tune the shape of the produced particles and the rate
of formation in a controlled way. The data are supported by atomic
force microscopy and transmission electron microscope observations.
