Growth of Bi-Ti-O particles by ion implantation

Abstract

Oxide nanoparticles of Bi-Ti-O system were fabricated in TiO₂ host material by ion beam irradiation. The implanted nanoparticles were evaluated by high-energy X-ray diffraction. The irradiated Bi ions were implanted in the TiO₂ as Bi₂O₃. The implanted Bi₂O₃ were changed to Bi₂Ti₂O₇ through heating process. The host TiO₂ was not damaged seriously by the Bi-ion irradiation owing to its diffuse crystal system. This technique can be used to make the ferroelectric nanoparticle in the paraelectric host material and realize the structure of magnetostrictive material similar to SmFe₂.
