OperandoRaman experiments were also performed in an effort to track, in real-time, the evolution of polysulfides and sulfur. As shown in Fig.3c, the Raman peaks of the polysulfides decreased, followed by an increase of the peaks from sulfur at 1200 s. The regions at 220 cm−1(red...

In principle, Raman features, such as position, FWHM, and intensity of Raman peaks, are sensitive to temperature, which continuously changes with temperature varying. Raman spectra obtained at different temperature are different to each other, which can provide valuable information. The FWHM and peak...
Peaks in the Raman spectrum of the NiSSealloy can be assigned to stretching and rotational modes of the S-S, Se-Se and S-Se pairs. The stretching vibration of the S-Se pairs shifts almost linearly from 400 cmfor NiSto 330 cmfor NiSe. There is an accidental degeneracy between the S-S...

The Raman spectrum of CdS nanoparticles clearly shows first, second and third order LO Raman peaks when excited using the wavelength of 488 nm. The red shift of the Raman peaks in nanoparticles compared to that of bulk CdS may be attributed to optical phonon confinement. 展开 ...
The preliminary assignment of the Raman peaks in the measured cervical secretion spectra indicated changes in specific biomolecules between the groups, and we analyzed them according to their differences. The specificity of the airPLS-PLS-GA-SVM model was 100 %, the sensitivity was 94.4 %, and ...
For precise stress measurements, the thermally induced shift of Raman peaks must be characterised in detail. In addition to external heating, the measurement itself may affect the sample temperature because the focused, intense light can locally heat the sample. Local heating must be taken into ...
Anticounterfeiting labels based on physical unclonable functions (PUFs), as one of the powerful tools against counterfeiting, are easy to generate but difficult to duplicate due to inherent randomness. Gap-enhanced Raman tags (GERTs) with embedded R
This peak could be attributed to a transition between vibronic states of carbon. In the PL spectra of annealed films, no shift of PL peaks was observed with increasing measurement's temperature (from 6 to 300K). 展开 关键词: Experimental/ annealing carbon nanotubes fullerenes nickel ...
