Characterization of Luminescence Properties with the Vulcan Cathodoluminescence Detector

The Vulcan Cathodoluminescence Detector is designed for nano-scale characterization of luminescence properties of materials. It is used in the transmission electron microscope for collecting, detecting and analyzing cathodoluminescence.

The detector is equipped with miniature mirrors that allow convenient installation of the system in most of the mainstream TEM/STEM instruments. It allows cryogenic cooling of the specimen which improves luminescence efficiency, minimizes the line width of spectral features from different specimens and damages resulting from an electron beam.

The morphology and microstructure of the samples can be directly correlated with luminescence properties. The detector is compatible with Gatan's electron energy loss spectroscopy products, enabling correlation of absorption and emission processes.

By capturing and analyzing low energy photons that are emitted by specimens as they interact with a high energy electron beam, the Vulcan Cathodoluminescence offers insights into the material's luminescence properties to a sub nanometer resolution.
