Characterisation of gold nanoparticles on substrate

This thesis investigated the interaction between light and gold nanoparticles, for gold nanoparticles sitting on a variety of surfaces. The work was both experimental and theoretical in nature. Using a custom designed experimental set-up we were able to probe the interaction of light with individual nanoparticles. We were also able to predict the interaction of light with gold nanoparticles sitting on graphene substrates. The work presented lays the groundwork for more extensive investigation of surfaces enhanced by the addition of gold nanoparticles.
