A 2D platform of molybdenum, sulfur and selenium is adept at detecting biomolecules via surface-enhanced Raman spectroscopy. Its nonmetallic nature helps by curtailing background noise. A sandwich ...

In this experiment, solid α-sulfur was positioned on an aluminum tray and subjected to heating with a hot plate. Raman spectra were subsequently acquired using both the E-grade probe and the i-Raman ...

The easiest to produce and most common are forms α, β and λ. A sample of α sulfur was placed on a microscope slide and then heated with a hot plate while measuring the Raman spectra with the THz-Raman ...

However, this reduces the sensitivity of low-cost silicon CCD detectors at longer wavenumbers, making it difficult or impossible to view the "stretch" section of the Raman spectra (2000-4000 cm-1).

Our instrument is especially optimized for fast hyperspectral imaging of complex samples and materials, where a full Raman spectrum is collected at every pixel. This technique, combined with advanced ...
