“…An estimation of this parameter can be obtained using the degenerate electron gas model, which was used to describe the NL response of metallic nanospheres [31,32]. This assumption is valid if we consider that, in direction y, the free mean path across the NE is the same for the nanosphere and observe that the nanosphere PRP and the NE PRP due to the TOM coincide spectrally.…”

Linear and nonlinear (NL) optical properties of colloids containing metallic core-dielectric shell nanoellipsoids (NEs) were studied using the MaxwellGarnett model. Influence of the NE geometry and the linear refraction index of the shell and the host on the linear optical properties and the enhancement factor due to the local field factor of metallic NEs in aqueous solution were analyzed. The expression for the third-order NL susceptibility for this composite material was obtained based on the NL response of aligned NEs. Results show that the plasmon resonance peak (PRP) and the enhancement factors can be tuned changing the NE geometry and the dielectric properties of the shell and the host.

Nonlinear third-order susceptibility χ (3) eff of composites materials having alternated layers of dielectric and plasmonic nanostructures of gold nanoparticles was theoretically studied using the effective medium theory and the degenerate electron gas model. Real and imaginary parts of χ (3) eff for the proposed composite material were calculated for the spectral region around the plasmon resonance of gold nanoparticles. The results reveal an enhanced nonlinear optical response compared with the obtained one for individual layers, as well as a reversal signal of χ (3) eff for different volume fraction conditions.
