Gold nanoparticle liquid crystal composites: synthesis, characterisation and optical nonlinearities

Gold nanoparticle liquid crystal composites: synthesis, characterisation and optical nonlinearities
Gold nanoparticle liquid crystal composites: synthesis, characterisation and optical nonlinearities
This thesis presents a theoretical and experiment investigation into the optical properties of gold nanoparticle liquid crystal composites. The experimental work can be divided into four sections; the synthesis of the nanoparticles, the creation of the gold nanoparticle liquid crystal composites and the investigation into their electro-optical properties and the nonlinear properties of hybrid photoconductive cells.

A large variety of gold nanoparticles were chemically synthesised with varying size distributions and functionalized. The samples functionalized with chemicals containing aromatic chemical groups were observed to aggregate. The optical properties of these aggregates were investigated by measuring their absorption and scattering efficiencies. The samples displayed a decrease in
their molar absorption coefficient from 10 cm
