Spectroscopy & Optical Analysis
Photoluminescence Spectroscopy (PL)
A non-destructive optical technique used to probe electronic structure and crystalline quality. Electrons excited by high-energy photons emit light as they relax. Intensity and wavelength are used to determine bandgap energies and identify structural defects or impurities.
Sample requirements
- PL is listed as in the installation phase.
- A published rate is marked Pending.
- A PL proforma is not yet available.
- Contact the facility before preparing a PL sample.
Availability should be confirmed with NS&TD before submission.
