Core facility (CF)

Short Description

The method pool of the spectroscopic methods in the core facility spectroscopy is an important pillar for the characterization of solid and liquid sample systems, and complementary to diffraction methods and to different imaging methods.

The core facility spectroscopy consists, among other things, of several Raman spectrometers and FT-IR spectrometers for studies by means of vibrational spectroscopy, of a photoluminescence spectrometer system for the qualitative and quantitative investigation of various luminescence (fluorescence / phosphorescence) phenomena, and of an EPR spectrometer for electron paramagnetic resonance spectroscopy.

The spectroscopic methods used allow the investigation of both macroscopic and microscopic samples (solids, liquids, gases, both inorganic and organic). Depending on the spectroscopic method used, the temperature of the samples can be set at temperatures between -180 ° C and 300 ° C using cryostats or thermostats.

The infrared spectrometers can be used in the FIR, MIR and NIR spectral range and are equipped with an ATR unit. In addition, confocal Raman microscopy measurements are possible in combination with atomic force microscopy.

The photoluminescence spectrometer system FLS980 (Edinburgh Instruments) is based on a fully automatic main unit for the UV-Vis-NIR range and a steady state mode operation. It is modular in design and due to its large sample chamber with 6-axis access it is particularly flexible for sample systems of various types. Luminescence processes in the range between 1 μs and 10 seconds can be monitored using a multi-channel technique. A double monochromator system is used for scattered-light-suppression and allows a particularly reliable examination of particle powders and other highly scattering sample systems.

Methods & Expertise for Research Infrastructure

Vibrational spectroscopy (Raman spectroscopy and infrared spectroscopy as mutually complementary spectroscopic techniques in the visible and infrared spectral range) is based on the spectroscopic investigation of vibrations of atoms bound within molecules or crystal lattices, and is used for the characterization and analysis of solid, liquid and gaseous samples (both organic and inorganic) within the disciplines of physics, chemistry, materials science, biosciences and forensics. The samples can usually be examined non-destructively.

Photoluminescence spectroscopy is a particularly sensitive method for investigating the electronic properties of molecules in different aggregate states. In addition, this method is suitable for investigating defect-related electronic transitions in semiconductors and isolators. The expertise and experimental equipment available in CF spectroscopy is available for the qualitative and quantitative investigation of various luminescence (fluorescence / phosphorescence) phenomena.

The electron paramagnetic resonance (EPR) spectroscopy belongs - as the related NMR spectroscopy - to the group of the magnetic resonance spectroscopies. It investigates the behavior of substances with unpaired electrons in an external magnetic field. By means of EPR spectroscopy, organic and inorganic radicals, transition metal compounds and defects in the solid, liquid and gaseous state can therefore be investigated.
