Investigate materials with cathodoluminescence (CL)

If you are studying ceramics, dielectrics, and (compound) semiconductors or develop devices and functional materials, such as scintillators, phosphors, high-power electronics light-emitting-diodes, diode lasers, and solar cells, you need solutions that can help you to efficiently analyze these materials. Cathodoluminescence emission can be used to explore many fundamental properties of matter.

It is a great technique for studying light transport, scattering, electronic structure of a material, resonant phenomena and much more. Learn more about your samples with powerful CL solutions, which will support your fundamental studies, quality control process or failure analysis.

What results can I achieve with cathodoluminescence?

Cathodoluminescence imaging is a powerful technique for studying both bulk and nanostructured materials. Various imaging modes of our CL detectors allow you to collect intensity (cathodoluminescence intensity mapping) and visualize the full emission spectrum (with hyperspectral imaging). This can be beneficial for studying semiconductor materials to see the materials performance for LEDs for lighting and displays, for example.

With the SPARC Compact system we did several hundred CL measurements per week and really managed to develop methods for quick analysis of the data.
