Raman spectroscopy of ball-milled TiO2

Evolution of photo-catalytic properties of reactive plasma processed nano-crystalline titanium dioxide powder

“…The most intense lines of rutile at 450 and 612 cm À1 can also be seen in the figure, with the line at 612 appearing as a shoulder in the anatase peak of 640 cm À1 . These results agree quite well with those reported in literature [16,17].…”

Bactericidal effects of reactive thermal plasma synthesized titanium dioxide photocatalysts

“…The most intense lines of rutile at 452 and 612 cm -1 can also be seen in the figure, with the line at 613 appearing as a shoulder in the anatase peak of 640 cm -1 . The results are in good agreement with A. Gajovic and co-workers [22,23].The characteristic bands due to the anatase phase are more intense than those of rutile in the as-synthesized TiO 2 nano powder is in agreement with the results of X-ray diffraction.…”

Synthesis and Raman spectroscopy study of TiO2 nanoparticles

“…Another possibility is to look closely at the Raman bands that appear in the low-wavenumber zone (Fig. 7) due to acoustic-phonon confinement [18]. Based on theoretical results, Duval et al [19] showed that the particle diameter is inversely proportional to the peak position (Fig.…”
