| Outline of Final Research Achievements |
We carried out spectroscopic characterization and temperature simulation of a nano-supercritical layer formed around the gold nanoparticles when the particles are subjected to pulsed-laser irradaition in aqueous solution. We observed the formation of such layers with smaller refractive indecies than water using a picosecond transient extinction spectral measurement. We prepared gold-silica and gold-silver core-shell nanoparticles by laser irradiation under the pressure of 60-100 MPa. The result demonstrated that the nano-supercritical layer is useful for the fabrication of advanced nanomaterials.
