Research Abstract |
Well-defined Au metal dimer arrays were successfully fabricated for obtaining the optimal local surface plasmon and consequently highly localized electromagnetic field. We demonstrated that such highly-polarized electromagnetic field in the gap induces not only relaxation of forbidden excitation for the molecule but local photo chemical reaction. These results provides us fundamental feature related to the strong photon-molecule coupling field (SPMCF) at metal nano-gap, and will contribute to the development of future photochemistry.
