19th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM 2018), Erlagol, Altai Republic, 29 June - 3 July, 2018 : proceedings P. 3-7Abstract: Crystal structure and optical properties of titanium
dioxide prepared via pulsed laser ablation of metallic Ti in
water were investigated. The ultrafine powder obtained after
drying the ablated dispersion consisted of dark blue
nanocrystalline TiO2 containing anatase and rutile phases
with an average particle size of 5-10 nm. This material
exhibited an intense additional absorption in the visible
region, which is associated with the presence of a large
number of defect states, namely different types of oxygen
vacancies. The effect of heat treatment on the structural and
optical properties of TiO2 was studied.
