Nanoscale Imaging of Light-Matter Coupling Inside Metal-Coated Cavities with a Pulsed Electron Beam

Fluorescence decay dynamics inside opaque, metal-coated nanocavities can be spatially resolved using excitation with a focused pulsed electron beam. The cover illustrates the launching of the electron pulses, their penetration of the metal coating, and their subsequent nanoscale excitation of embedded gain medium inside the cavity. As a consequence, the gain medium luminesces with a decay rate that depends strongly on the precise location inside and size of the cavity.
