Abstract
There are two parts in this thesis, including study of optical properties of gold nanoshells, and the application of nanoimprint techniques for surface plasmonic devices.
In the part of study of optical properties of gold nanoshells, we measure the ellipsometric parameters of gold nanoshells with different particle density, and different hollow degree by using varing angle spectroscopic ellipsometer (VASE), and then get the optical constants (n,k) by data fitting. Finally, we compare the optical constants of gold nanoshells with conventional gold nanoparticles.
In the part of study the application of nanoimprint technique, we successfully use the double imprint technique to fabricate two dimensional wavy patterns on gold film, and enhance the transmittance of gold film by surface plasma effects., We can also enhance the transmittance of gold film in the visible region by choosing suitable experimental parameters, including periods of molds, and imprinted pressure.
