Outline of Final Research Achievements

In this study, the photo-thermal deformation process in semi-shell nanostructures was investigated for developing dynamic plasmonic devices. Our results are summarized as follows. (1)We experimentally demonstrated that the plasmonic resonant wavelength can be tuned by the incident light intensity in the Au-SiO2 semi-shell nanostructures. (2)An alloy of Au75%-Sn25% has a great potential to reduce the required light intensity for the photo-thermal deformation process.
