Vulcan Cathodoluminescence Detector
Gain insight into your sample’s optical and electronic properties.
Characterize luminescence properties of materials at the nanoscale. The Vulcan™ detector is a cathodoluminescence (light) collection, detection, and analysis system for the (scanning) transmission electron microscope.
- Miniature mirrors enable installation in most mainstream TEM/STEM instruments
- High sensitivity allows easy analysis of luminescence from a wide range of samples
- Directly correlate sample morphology and microstructure with luminescence properties
- Measure electronic properties of luminescent materials at meV energy resolution including: band gap, and defect and quantum confinement effects in semiconductors
- Reveal surface plasmon resonance modes of nanoparticles in any STEM instrument
- Cryogenic cooling of the specimen increases luminescence efficiency, reduces damage caused by the electron beam, and reduces the line width of spectral features from many specimens
- Compatible with electron energy loss spectroscopy products from Gatan to allow correlation of absorption and emission processes
