“…Many observations are consistent with a picture of light emitted by junction plasmons that are excited by the tunneling electrons as the source of the observed emission. 4,10,[197][198][199][200][201][202][203][204][205][206][207][208] This interpretation is supported by a substantial body of theoretical work. [209][210][211][212][213][214][215] Obviously, other fluorescent modes can also be excited.…”

The interaction of light with molecular conduction junctions is attracting growing interest as a challenging experimental and theoretical problem on one hand, and because of its potential application as a characterization and control tool on the other. It stands at the interface between two important fields, molecular electronics and molecular plasmonics and has attracted attention as a challenging scientific problem with potentially important technological consequences. Here we review the present state of the art of this field, focusing on several key phenomena and applications: using light as a switching device, using light to control junction transport in the adiabatic and non-adiabatic regimes, light generation in biased junctions and Raman scattering from such systems. This field has seen remarkable progress in the past decade, and the growing availability of scanning tip configurations that can combine optical and electrical probes suggests that further progress towards the goal of realizing molecular optoelectronics on the nanoscale is imminent.
