Instrumentation

  • Raman and photoluminescence set-up consisted of a triple monochromator (DILOR ΧΥ) with gratings of 1800 lines/mm and a CCD (EG&G 1433-C) liquid-nitrogen-cooled detector.
  • Raman spectrometer RAMALOG 5 equipped with a Peltier-cooled photomultiplier tube with GaAs photocathode and a triple-monochromator that covers the wavelength range 12000 – 28000 cm-1 (8500-3500Å), fully automated and PC controlled.
  • Two Ar+ Lasers of Spectra Physics 2W.
  • One Kr Laser of Lexel 1.5 W.
  • One cryostat accompanied by a diffusion pump of Cryogenic that works down to 20 K.
  • Gas membrane driven diamond anvil cells, micro-tensiometers for the application of mechanical deformation (uniaxial, biaxial).
  • Optical and mechanical systems controlled by PC
  • Optical components and systems
  • Other sources of Light as well as solid state and He-Ne Lasers
  • Electronic Systems (oscilloscopes, power supplies, etc.)
  • Monochromators, spectrometers
  • Full range of microscopes
  • Diffractometers, interferometers and other optical instruments

Additionally, laboratory members are frequent users of European and Japanese synchrotron facilities, towards materials’ studies by means of X-ray diffraction and spectroscopy.
