| Outline of Final Research Achievements |
Hydrophobic point decoration was performed onto hydrophilic surface of gold nanoparticles with Langmuir-Blodgett film. Gold nanoparticle dimers (plasmonic dimers) were self-assembled through hydrophobic interaction. The samples were observed with an atomic-force microscope. It was observed that not only dimers but also monomers, trimers, aggregates were formed, and the ratio of the plasmonic dimers was about 13% among them. Scattering spectrum of a plasmonic dimer was measured, where two different plasmon resonances were observed derived from the long and short axis, respectively.
