Outline of Final Research Achievements

In this study, coexistence of plasmon resonances and d-functions was achieved by fabrication of layered nanodots consisting of sp-metals and d-metals. We demonstrated various functions with strong plasmon resonances in this structure; for example, UV-induced tuning of plasmon resonances in near infrared region and magnetization-induced tuning of plasmon resonances in visible wavelength region were experimentally demonstrated.
These results clearly show that the multi-functional plasmonic materials open up a novel technological aspect of nano-photonics and plasmonics.
