Nonlinear optical characterization of the gold nanoparticles coated by the thiols
AbstractStructured nanomaterials have great potential applications based on their unusual optical properties, such as a negative refractive index , plasmon waveguiding  or nonlinear optics. In this paper we present the nonlinear optical characterization of gold nanoparticles coated by thiols with the ratio of mesogenic to n-alkyl thiols varying from 1:2 to 1:1 in a toluene suspension using the Z-scan technique. The type of mesogenic molecule in the metal coating had a profound influence on the gold-cluster self-assembly. To check how these clusters affect the nonlinear properties we use two different polarizations of a laser beam - linear and circular.
