Cathodoluminescence in Geological Applications

Webinar Content

Cathodoluminescence spectroscopy (CL) is a powerful tool for the micro-characterization of rocks and minerals, providing unique contrasts complementary to other electron microscopy-based techniques, such as backscattered electron imaging and energy/wavelength dispersive x-ray spectroscopy.

In this webinar, we discuss the physical background of CL emission in rocks, sample preparation, and the typical CL workflow.

We show examples of how the technique can be applied to:

• Sedimentary rocks
• Gemstones
• Zircons.

Speaker – Dr. Toon Coenen

The webinar will be hosted by DELMIC’s in-house application specialist, Toon Coenen. Toon studied at University College Utrecht. After obtaining his BSc degree there he went on to study chemistry and physics at Utrecht University where he obtained a MSc degree in 2010. He continued for a PhD at the FOM Institute AMOLF in Amsterdam, the Netherlands, in 2014 in professor Albert Polman’s group. There he co-developed the first version of the SPARC cathodoluminescence detection system and used it to investigate the nanoscale optical properties of various metallic and dielectric nanostructures. During his PhD he also was a visiting scientist at Stanford University in the group of professor Mark Brongersma, performing EELS experiments on plasmonic structures. He now works at Delmic BV as application specialist, developing novel cathodoluminescence applications and improving the cathodoluminescence system as a whole.
