## Description

- description: Photoluminescence Excitation spectroscopy (PLE) is crucial in understanding
    materials photo- physics, which play an important role in devices design and optimization.
    Unfortunately, PLE is handicapped by the diffraction limit when addressing the
    nanometric properties of matter, and no equivalent near-field spectroscopy has
    emerged so far. By coincidentally measuring the energy loss of a relativistic
    electron on optical materials (plasmonic nanoparticles, luminescent 2D materials)
    and their subsequent light emission, we demonstrate the possibility of making
    cathodolumines- cence excitation spectroscopy, a natural counterpart of PLE with
    a resolution better than 10 nm. The information retrieved should prove unvaluable
    for the understanding materials optics at the nanometer scale.
