This thesis proposes a novel way to catch light energy using an
ultrasmall nanostructure. The author has developed photon-materials
systems to open the way for novel photoexcitation processes based
on the findings obtained from in-situ observation of the systems in
which localized surface plasmon (LSP) and molecules interact
strongly. The highly ordered metal nanostructure provided the
opportunity for anisotropic photoexcitation of materials in an
eccentric way. The optimization of the systems via nanostructuring
and electrochemical potential control resulted in the novel
excitation process using LSP to realize the additional transition
for photoexcitation. Furthermore, excited electronic states formed
the strong coupling between LSP and excitons of molecules. This
thesis will provide readers with an idea for achieving very
effective processes for photon absorption, scattering, and emission
beyond the present limits of photodevices.
