Correlated blinking of fluorescent emitters mediated by single plasmons
Physical Review A, 2017•APS
We observe time-correlated emission between a single CdSe/CdS/ZnS quantum dot
exhibiting single-photon statistics and a fluorescent nanobead located micrometers apart.
This is accomplished by coupling both emitters to a silver nanowire. Single plasmons are
created on the latter from the quantum dot, and transfer energy to excite in turn the
fluorescent nanobead. We demonstrate that the molecules inside the bead show the same
blinking behavior as the quantum dot.
