Method Based on Continuous Artificial Dry and Humid UV Treatments to Reduce the Luminescence Background in the Raman Spectra of Plastics

Journal of Raman Spectroscopy, EarlyView.
We propose an UV photobleaching pretreatment to reduce the strong luminescence in the Raman spectra of plastic samples. Our protocol proves its efficiency whatever the luminescence origin (from the pigments or from a surface biofilm) but requires a careful optimization of the illumination conditions (UV wavelength, time, humidity) to reach the ...

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

Journal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms.

Strain Imaging of GaAs by Stimulated Raman Scattering Microscopy

Journal of Raman Spectroscopy, EarlyView.
Telecom‐wavelength stimulated Raman scattering (SRS) microscopy is developed for high‐throughput, nondestructive characterization of gallium arsenide (GaAs). By overcoming optical absorption limits of conventional Raman systems, this technique enables precise visualization of LO phonon frequency variations (< 0.2‐cm−1$$ {}^{-1} $$ precision).

Inter‐Theta‐Gram Spectroscopy: A General Super‐Spectral‐Resolution Scattering Method Demonstrated on Diamond

Journal of Raman Spectroscopy, EarlyView.
Inter‐Theta‐Gram spectroscopy enables super‐spectral‐resolution Raman analysis by jointly reconstructing the excitation laser line and Raman peak during an etalon angle scan, yielding internally referenced Raman shifts. Demonstrated on lab‐grown versus natural diamond, it resolves 0.1–0.2 cm−1 Raman‐shift offsets that are invisible in conventional ...

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

Journal of Raman Spectroscopy, EarlyView.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.
