A new method has been developed for detecting the light emitted by the tunnel junction of a scanning tunneling microscope. Resonant features have been found on plots of the light intensity versus the applied voltage for Au-Au, Ag-Ag, Au-Pt, and Ag-Pt tunnel junctions. These features can be linked with the excitation of localized surface plasmons.
