| Outline of Final Research Achievements |
Insertion of carbon atoms into the Pd nanodisks was carried out to confirm the plasmon peak shift by dissolving another element into the Pd nanodisks. When the Pd nanodisks of 79 ± 16 nm in side and 23 ± 3.2 nm in thickness were reacted with trimethylamine-N-oxide, an insertion of carbon atoms into the lattices of Pd nanodisks was observed. By changing the reaction conditions, the Pd sublattices were found to possess either a hexagonal close-packed structure or a cubic close-packed structure. Furthermore, it was found that the change in the dielectric constant of the Pd nanodisks by the carbon insertion induced the red-shift of the plasmon peak. This result means that the light irradiation with longer wavelength than the plasmon peak of Pd nanodisk is necessary for enhancing the hydrogen storage ability.
