As is known, the high-frequency region (800–1200 cm −1 ) of the spectra of alkali silicate glasses and melts is characterized by a series of Raman bands originating from the stretching vibrations of various units. Mammone and Sharma (1979) obtained Raman spectra of Ge02 glass in a diamond anvil cell at pressures up to 78 kbar. For pressures above 40 kbar, the spectra seem to show a broadening of major bands, and general loss of band structure, not observed for quenched Ge02 glass (Sharma et al., \919a). Glass of the Na2O – B2O3 – SiO2 system with a B2O3 content from 20 to 40% was investigated by high-temperature Raman spectroscopy. It was shown that when the boron oxide content was gradually Raman-effekten.

When you have to use a transparent vessel, you can select a glass type with a weak Raman signal (e.g. quartz is weaker and less intrusive at 785 nm than standard glass).

A Raman spectroscopic study of borosilicate glass was reported by Konijnendijk and Stevels [7, 8]. The Raman bands at frequencies between 600 and 950cm -x were tentatively assigned to 9 1981 Chapman and Hall Ltd. 2689 High-temperature Raman spectroscopy is a useful method for investigating not only the glass structure but also the melt structure over a wide temperature range [5–15]. As is known, the high-frequency region (800–1200 cm −1 ) of the spectra of alkali silicate glasses and melts is characterized by a series of Raman bands originating from the stretching vibrations of various units.

The spectra collected can be challenging to interpret because certain source laser wavelengths may be absorbed by specific pigments, lead Raman-spektroskopi används för att kemiskt analysera material i fast form, flytande form och gasform, och är ett ovärderligt verktyg för att identifiera och verifiera material.

Raman spectroscopy of glass usually does not provide specific structural information, but it can often identify the presence of terminal anions, like the non‐bridging oxygen (NBO or O NB ) ions in oxide glasses, through the presence of typical high‐frequency 2020-07-01 · Raman depth profiles of Na20 glass show the similar evolution in comparison to Na16 glass.

published in March 1928 by Raman & Krishnan.[2] Almost simultaneously, soviet physicists Landsberg & Mandelstam observed the same effect in crystals.[3] The phenomenon was named after the Indian physicist Chandrasekhara Venkata Raman, who was awarded The Nobel Prize in weak Raman scatterers and so it is extremely important to note the scan conditions when comparing the Raman spectra from different samples. As an example, it is accepted that glass has a relatively weak Raman spectrum. However, the spectrum of glass can be made to appear strong by doing multiple scans (Figure 1). Poly(methyl methacrylate) (PMMA) is a very versatile polymer which is used as a glass substitute or as an economical alternative to polycarbonate for many types of important applications, due to its particular physical properties. In this study we deal with the Raman spectroscopic characterization of the gla Glass 01 Raman analysis of laser-processed glass materials Laser processing provides a fast, non-contact and flexible method of modifying and patterning materials, from glasses to metals. Micro-machining, thin layers ablation, two-photon polymerization are just a few examples of what has already been demonstrated.
