(e,f) Raman hyperspectral imaging of the same area showing selectively the strength of the G0 and the G± band, respectively. Scale bars, 20 mm. Cavity-enhanced Raman imaging. We expand this capability to perform hyperspectral imaging. Therefore, we record cavity- enhanced Raman spectra such ...
The algorithm manages hundreds of spectra simultaneously and provides statistical information (distribution of Raman shifts, average values of shifts and relative intensities, standard deviations, correlation between different peaks, etc.) of the main spectral features defining the structure and electronic ...
图5 各煤样Raman光谱特征Fig.5 Raman spectra are composed of first-order regions, with the main peaks suggested (graphite G peak and D1 to D4 defect-activated peaks), and corresponding second-order regions resulting from overtone scattering 表3 各煤样Raman光谱参数 Table 3 Raman spectroscopic par...
The PL spectra are characterized by a two-band structure. The high-energy band in the range from 300 to 350 nm is due to the exciton pair annihilation and may characterize the band gap of SnO x nanocrystals as a function of their diameter. In the red spectral region (from 600 to 700 ...

Micro-Raman spectra of single-walled carbon nanotubes in the range of two-phonon 2D bands are investigated in detail. The fine structure of two-phonon 2D bands in the low-temperature Raman spectra of the mixture and individual single-walled carbon nanotubes is considered as the reflection of str...

Performance of Raman image-activated cell sorting We validated the basic performance of the RIACS as follows. First, we performed high-purity enrichment of polymer particles (see “preparation of polymer particles” in the Methods section for details). Figure 2a shows SRS spectra of polystyrene (...
