TDT. E. Drozdova PSP. B. Sergeev

Key Points

The study aims to investigate how fluorination affects the Raman spectra of titanium.
Analyzed Raman spectra of titanium foils post-fluorination
Measured intensity changes after exposure to humid air
Identified spectral bands related to fluorine and titanium compounds
Identified bands at 905, 1795, and 2680 cm−1 associated with fluorine below the oxide layer
Observed decrease in intensity of fluorine-related bands with humid air exposure
Detected increasing bands corresponding to titanium oxynitrides and oxyfluorides

Abstract

The behavior of Raman spectra of titanium foils after their fluorination was studied. It is shown that the bands at 905, 1795 and 2680 cm−1 belong to fluorine located under the titanium oxide nanofilm. Contact of fluorinated foils with humid air leads to a decrease in the intensity of these bands. At the same time, the bands of titanium oxynitrides and oxyfluorides appear and increase.
