Growth of Bi-Ti-O particles by ion implantation

Abstract

Oxide nanoparticles of Bi-Ti-O system were fabricated in TiO 2 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 TiO 2 as Bi 2 O 3 . The implanted Bi 2 O 3 were changed to Bi 2 Ti 2 O 7 through heating process. The host TiO 2 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 SmFe 2 .
