| Outline of Final Research Achievements |
We have successfully elucidated that oxygen evolution was induced as a result of water oxidation in the photoelectric conversion system which employs gold nanostructures showing localized surface plasmon (LSP) as an optical antenna. It was also clarified that the water oxidation is induced at a restricted nanospace near gold/semiconductor/water interface, which were visualized by photoelectrochemical polymerization. These principles have developed artificial photosynthesis, so that overall water splitting and ammonia synthetic systems were successfully constructed. On the other hand, we have clarified that quadrupole plasmon resonances and optical antennae utilizing strong coupling between LSP and molecular system shows efficient light confinement function, which were studied by the developed time-resolved photoemission electron microscopy in this study. Furthermore, we have successfully developed all solid state plasmonic photovoltaic cell using nickel oxide as a hole transport layer.
