In the Raman spectrum of the WO3-20SiO2-0.5 (Fig. 5B), two strong peaks at around 700 cm−1 (ö) and 800 cm−1 (•) correspond to the stretching modes of W–O–W [63]. The positions of these peaks are shifted compared to those in the Raman spectrum of WO3-Comm due to...
Raman spectrum of the anatase TiO2/SiO2 nanocomposite coating elaborated from a 2 µL·min−1 HMDSO delivery rate on a PEN substrate. The Raman spectrum of an uncoated PEN foil is also plotted as a reference. Full size image Characterization of the anatase TiO2/SiO2 nanocomposite coating ...
(Fig. S5); not only Si–C bonds are observed at approximately 838 cm−1, but also Si–O absorption bands appear at 1095, 779, and 455 cm–1[41]. There are two characteristic peaks at 795 and 972 cm− 1in the Raman spectrum of the SiC@SiO2NFA (Fig.3c), corresponding to ...

The pure synthetic end-member of antigorite was studied by in-situ Raman spectroscopy in a diamond anvil cell. It can be metastably compressed up to 10 Gpa at room temperature without occurrence of phase transition or amorphization. The spectrum in the OH region is simpler than in natural anti...
Nanoscience and NanotechnologyMonolithic mesoporous silica glasses were synthesized. The presence of Cu2+ and Fe3+ cations during the synthesis of sol-gel precursors leads to different morphologies and pore sizes. The materials are characterized via IR and Raman scattering spectra to detect surface ...
The Raman spectrum measured at position 3, which is far away from the surface feature, shows a higher compressive stress (spectrum 3 in Figure 14b). Figure 14. Raman characterization of the area shown in Figure 13a. (a) Raman map of Si-nc (integration from 515 to 530 cm–1) obtained ...
