Raman & Luminescence Spectroscopy System

Raman and Luminescence Spectroscopy System

Quantum Design's new Spectroscopy System combines Raman and Photo-Luminescence spectroscopy with optical sample imaging in the variable temperature and magnetic field environment of the PPMS. Using this "turn-key" system, gaseous, liquid and solid materials, in bulk or thin film form, may be investigated. Raman spectroscopy is a non-destructive spectroscopic technique used to identify and explore vibrational, rotational, and other excitation modes in a sample. Raman spectroscopy is commonly used to identify crystalline materials by measuring their specific Raman "fingerprint." This is done by measuring the inelastic scattering of light. In crystalline samples, the inelastic gain or loss of energy produces narrow discrete peaks known as Stokes and Anti-Stokes peaks, respectively. Glasses, in contrast, have broad vibrational spectra that in turn give rise to broad Raman spectra. When using the versatile PPMS Spectroscopy System, the study of spin-lattice coupling in strongly correlated oxides as a function of temperature and magnetic field is made easy through the highly automated MultiVu interface.

  • Various Wavelengths (532, 785, and 850 nm)

Applications

  • Structural Identification
