Abstract:

105 keV Ti ions were implanted into SiO2 substrate, and were then subjected to thermal annealing in oxygen atmosphere. The formation, structure, distribution, optical absorption property as well as photocatalytic performance of the formed nanoparticles (NPs) were characterized using various techniques such as ultraviolet-visible spectroscopy, grazing incidence X-ray diffraction spectroscopy, transmission electron microscopy and atomic force microscopy. The results clearly show that high-fluence Ti ion implantation into SiO2 along with thermal treatments in oxygen atmosphere could cause formation of TiO2 NPs, which mainly present rutile phase. Morphology of the synthesized TiO2 NPs depends strongly on the applied fluence of Ti ions. With the fluence increasing, the irregular and isolated NPs could be transferred into densely distributed TiO2 NPs, resulting in formation of particle-like thin films. In addition, the synthesized TiO2 NPs at higher fluence show a certain photocatalytic degradation performance on Rhodamine B solution.

Key words: Ion implantation, TiO2 nanoparticles, Annealing, Particle-like thin films
