The Raman spectrum of these layers is shown in Fig. 8(c), with the spectra normalized to the peak at 352 cm−1 and offset for clarity. This shows changing behaviour from monolayer to few-layer crystals that is consistent with FprigeuviroeuSs8r(eep) oanrtds2(6g,6)6.inThthe...
Raman spectra collected across the bubbles showed an intense and convolute absorption in the range 3000–2800 cm−1, associated with weaker bands at 1655, 1438 and 1297 cm−1, indicating the presence of fluid inclusions consisting of aliphatic hydrocarbons, alkanes and cycloalkanes, with ...

The 10−3 M R6G aqueous solution was prepared and the R6G solution of various concentrations such as 10−4, 10−5, 10−6, 10−7, and 10−8 M can be obtained by diluting it with deionized water. Figure 2(a) shows the SERS spectra of different-concentration R6G ...
Plotting the resultant Raman intensity against the Raman shift in wavenumbers gives rise to Raman spectra. As an example, we have shown the Raman spectrum of microglia, which are glial cells that act as phagocytes in the brain (Figure 1c). Importantly, this spectrum shows no peaks between ...

One more interesting property of the scheelite-type tungstate and molybdate crystals is the presence of two intense vibrational lines in their spontaneous Raman spectra: the most intense one corresponds to the above mentioned high-wavenumber (ν1) stretching mode (Ag) but the second line has a ...
In situ Raman spectra of different samples during CO2 capture were measured using a laser confocal Raman spectrometer (LabRAM HR Evolution, Horiba France SAS, Villeneuve d'Ascq (Nord-Pas-de-Calais Region), France). A carrier table attached to the measurement system was used to load samples ...
The laser power used was between 250–500 mW to avoid the influence of possible heating while the spot size on the samples was about 0.25 mm in diameter. The reflectance spectra of pSi PhC were measured by a UV–Vis–NIR spectrophotometer (Shimadzu UV-3600, Shimadzu Corp., Kyoto, Japan) ...
