UV / Visible spectroscopy: Experiments at low temperatures reveal the interaction between the electronic energy levels and vibrational modes in solids.

Infra-red spectroscopy : Low temperature IR spectroscopy is used to measure changes in interatomic vibrational modes as well as other phenomena such as the energy gap in a superconductor below its transition temperature.

Raman spectroscopy : Lower temperatures result in narrower lines associated with the observed Raman excitations.

Photoluminescence : At low temperatures, spectral features are sharper and more intense, thereby increasing the amount of information available.

Gas absorption : We have developed a special cryostat in partnership with Quantachrome Instruments to fit their autosorb-iQ gas sorption analysers.

Case study:

Dr Ken Haenen and Prof Jean Manca (Limburg University, Diepenbeek - Belgium) use the OptistatDN in combination with a FTIR spectrometer to perform Fourier Transform Photoconductive Spectroscopy FTPS. FTPS is a highly sensitive photocurrent method for materials with low optical absorption such as conjugated polymer and CVD-diamond films, which are developed for novel electronic, and bio-electronic applications.
