Delmic CL solutions offers a range of powerful and user-friendly cathodoluminescence detectors, which can help you learn more about plasmonics and metamaterials.
Plasmons are collective oscillations of conduction electrons in a metal. The electron beam that is used in cathodoluminescence (CL), acts as a highly localized broad-band excitation source of plasmons. This makes CL ideal for characterizing spectral characteristics of local optical resonances in plasmonic nanoparticles and metamolecules used as building blocks for e.g. metasurfaces and sensors. Furthermore, it can be used to map, dispersion, directionality, and/or polarization in plasmonic waveguides, metasurfaces, and metamaterials to name a few examples.
