Acceleration of nanofluids presents a potentially strong impact in mechanooptical
observations regarding the fascinating dynamic behavior of
nanoparticles contained in a liquid solution. The precipitation parameters
modulated by shape and size of hybrid nanostructures suspended in ethanolbased
samples were analyzed in this work. The nanostructures were integrated
by multi-wall carbon nanotubes decorated by silver nanoparticles. Refractive
and absorptive nonlinearities dependent on density and distribution of
nanoparticles in the host material were studied by the assistance of a vectorial
two-wave mixing experiment. Numerical and experimental optical results were
obtained for nanosecond pulses at 532 nm wavelength provided by the second
harmonic of a Nd:YAG laser system. Significant changes in the optical Kerr effect
together to the modification of the nonlinear optical absorption in the samples
were observed by the participation of the metallic nanoparticles in the studied
systems. Remarkably, interparticle interactions seem to importantly change the
plasmonic response of the nanofluids when gravitational or acceleration actions
played a key role for moving particular nanoparticle distributions. High
Resolution Transmission Electron Microscopy studies and UV-vis spectroscopy
evaluations were undertaken. Advanced platforms towards the development of
fantastic nanovehicles for drug delivering or ultrafast low-dimensional energy
transfer functions can be envisioned.
