What is Cathodoluminescence Website from Gatan

New Cathodoluminescence Website

Gatan have launched a new website called with cathodoluminescence resources, for TEM/SEM users and anyone interested in learning more about the technique.

What is Cathodoluminescence?

Cathodoluminescence, also known as CL, is a powerful microscopy technique for characterising composition, optical and electronic properties at the nanoscale. The technique has several key benefits:

  • Sub-nm spatial resolution.
  • Data correlates with structural information.
  • Provides a wealth of data: morphology (eg size, shape), composition, chemistry, crystallography, electronic properties and more.

More details are available in our article:

With systems from Gatan, CL can be added to your SEM or (S)TEM to access more information about your samples.

Resources Available on the Website

The new website from Gatan is designed to help you get the most from your cathodoluminescence experiments, and also to provide information to those unfamiliar with the technique.


An introduction to cathodoluminescence as a technique, when to use it and an overview of the various modes of operation, such as polarisation, time-resolved, ARCL and WARCL.


How CL can be used in various fields, with links to useful application notes and webinars:

  • Rocks, minerals and gems
  • Semiconductors – process development, nanostructures and devices
  • Nanophotonics
  • Ceramics, oxides and nitrides
  • Analysing radiation
  • Organic molecules – including biological specimens, pharmaceuticals and polymers

How To

How to prepare samples, perform experiments, optimise settings and analyse data, with tips and tricks. Includes how to collect maps, spectra and emission patterns, as well as spectrum imaging.


Search for publications, example images and videos related to your application or technique.
