What is spectrally and angular-resolved(also known as energy-momentum) CL?

In the last blog post we explained angle-resolved cathodoluminescence imaging, a technique which is used to acquire angular profiles and gain a better understanding of materials' optical properties. The imaging technique that we are focusing on this week combines information acquired with angle-resolved imaging and high-resolution spectroscopy. This technique is called Lens-scanning energy-momentum(LSEK) Imaging, or full Angle-Resolved Spectroscopy, and it allows collecting a full emission spectrum for each emission angle. This new imaging technique is now available with the SPARC system. Keep reading if you would like to understand how it works and what results can be achieved.

What is Angle-Resolved Cathodoluminescence?

In our last blog post we presented all six cathodoluminescence imaging modes that can be used with our SPARC detector to analyse and observe samples. In this blog post we are going to focus on angle-resolved cathodoluminescence, a technique which allows to create angular profiles of the samples.
