silicon dioxide clustersIR and Raman spectramolecular-dynamic methodThe effect of absorbed water on the dielectric properties of silicon dioxide nanoparticles is studied by the molecular dynamic method. It is demonstrated using the model of flexible molecules that increasing the number of water molecules...
Raman spectrasilicon compoundsWe have measured Raman spectra of fluorine-doped SiO 2 (SiOF) films and quartz glass. From a comparison between Raman spectra of the SiO 2 film and quartz glass, it has been found that the SiO 2 film is under compressive stress and that it has more threefold ...
The calibration of the instrument was checked at the beginning of each analytical session using the 521 cm−1 silicon band. Laser power at the sample surface was checked using a COHERENT “LaserCheck” pen. Spectra were acquired in the 100–1800 cm−1 range (further details can be ...

Owing to the physical mechanism at their basis, Raman spectra are sensitive to any change in the material that alters the energy of optical phonons, like the breaking or formation of chemical bonds, phase transitions, residual strain/stress, or the presence of lattice defects. One of the ...

The intensity of the Raman spectra is amplified by the use of the surface-enhanced Raman scattering (SERS) technique. While the use of silver sols results only in a limited reproducibility of the Raman line intensities, lithographically designed, nanostructured gold surfaces used as SERS-active ...
'Raman spectra' refers to the characteristic patterns of light scattering that arise from interactions between a laser beam and the chemical composition of a sample. These spectra can be influenced by various factors such as excitation wavelengths and background fluorescence, and are commonly used in...
The Raman spectra of the hexagonal (β) and cubic spinel (γ) forms of Ge3N4, newly obtained by high-pressure synthesis, have been measured and are compared with zone-center phonon frequencies calculated using first principles methods in a plane wave pseudopotential local density approximation. Th...
