Cathodoluminescence (CL) spectroscopy 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 discussed the physical background of CL emission in rocks, sample preparation, and the typical CL workflow. We also showed examples of how the technique can be applied to sedimentary rocks, gemstones, and zircons. This webinar was hosted by our SPARC application specialist, Toon Coenen, and in collaboration with our Australian distributor, AXT.
