Metal nanoparticles embedded in insulating matrices have received an increasing interest in the last decade due to their peculiar optical, magnetic, and catalytic properties when the size becomes comparable to or less than the electron mean free path. Recently, oxide nanoparticles in insulators can be fabricated by combining the ion implantation and the thermal oxidation). In this method metal nano particles are formed inside of the insulators by ion implantation at first, then the metal nanoparticles are oxidized by thermally activated migration of oxygen in the insulators. In this study, we demonstrated the growth of Bi-Ti-O system by the Bi-ion implantation on TiO textured substrate. We performed the Bi-ion implantation with Takasaki Ion Accelerators for Advanced Radiation Application (TIARA) and the grown nanoparticles were evaluated by synchrotron X-ray at SPring-8.
