Spectroscopy Techniques and Applications

Raman

Raman is a molecular spectroscopy technique that can provides chemical and structural fingerprint information for a wide range of samples, including for example nanomaterials, polymers, powders, liquids or cells/tissues. Key Raman techniques include:

  • Spontaneous and stimulated
  • Surface Enhanced Raman Spectroscopy (SERS)
  • Surface Offset Raman Spectroscopy (SORS)
  • Tip-Enhanced Raman Spectroscopy (TERS)
  • Coherent Anti-Stokes Raman Scattering (CARS)

Luminescence

Luminescence spectroscopy is used for a large variety of applications including for example the study of metal complexes, organic LEDs (OLEDs), quantum dots, cell dynamics, stand-off detection of chemical compounds (e.g. explosives) or scintillators properties measurement. Key techniques include:

  • Fluorescence
  • Photoluminescence
  • Cathodoluminescence
  • Chemiluminescence

Absorption / Transmission / Reflection

Ultraviolet Visible Near-Infra red (UV-Vis-NIR) spectroscopy is useful to characterise the absorption, transmission, and reflectivity of a variety of materials such as pigments, biological, coatings, windows, filters, or analyse the dynamics of chemical reactions. Variations of these spectroscopy techniques include:

  • Transient absorption (pump/probe)
  • Diffuse Reflectance

OES and LIBS

Optical Emission Spectroscopy (OES) is a fundamental, non-invasive diagnostic technique for a wide range of plasma, and can provide information such as composition and species temperature and energy distribution.

Laser-induced breakdown spectroscopy (LIBS) is used to determine the elemental composition of various solids, liquids and gases. A high power laser pulse is focused on to a sample to create a plasma. Emission from the atoms and ions in the plasma is collected and analysed by a spectrograph and gated detector to determine the elemental composition or the elemental concentrations in the sample.

Microspectroscopy

Micro-spectroscopy covers a very wide range of spectroscopy modalities with the common character that the spectroscopic measurement is made on the microscopic scale. Andor spectroscopy systems are routinely used for Raman-based techniques including:

  • Micro- Raman and Fluorescence/Photoluminescence
  • Diffuse Scattering micro-spectroscopy
  • Multiphoton micro-spectroscopy

Non-Linear Spectroscopy

Non-linear (NL) spectroscopy encompasses a number of optical techniques that can be used to study for example interfacial and surface processes, ultrafast dynamic processes (pump-probe technique), light transport or assist in the understanding of nanoparticles/nanostructures unique optical properties. Key techniques include:

  • Second harmonic generation (SHG) spectroscopy
  • Sum-frequency generation (SFG) spectroscopy
  • Pump-probe transient absorption

Life Science - Biomedical

Optical spectroscopy can provide very specific analytical information in a non-invasive matter for a range of bio-samples, often as a complement to microscopy imaging (micro-spectroscopy) or visual inspection.

Field of applications include for example cancer cell in vivo and ex vivo screening and cancer diagnostics, non-invasive monitoring of patient bio-parameters or cell sorting.

Plasma Studies

Plasmas can be artificially produced by different means (e.g. laser ablation, coupling of capacitive / inductive power source to ionised gas). The understanding of their properties and dynamics is relevant to a number fields such as fusion, thin films deposition, micro-electronics, material characterization, display systems, surface treatment, fundamental physics, environmental & health.

Gated detectors can be used to determine optical parameters from which fundamental plasma properties can be derived. Accurate nanosecond-scale gating of image intensifier-based detectors can be used to sample plasma dynamics, or to isolate the useful plasma information generated by pulsed lasers.
