Cathodoluminescence Imaging Modes and Applications

Overview

Cathodoluminescence or CL is a rapidly growing technique that reveals properties of materials based on light-matter interactions at the nanoscale. Part of the reason for its growing popularity are the new modes of CL imaging that have recently become available that further extend the applicabaility of the technique. These techniques are made possible by the DELMIC SPARC cathodoluminescence system that can be retro-fitted to most SEMs.

For those of you who would prefer to watch than read, we have assembled a host of relevant videos/webinars that will take you through the various imaging modes, theory and applications .
