Abstract:
|
Non-radiative transfer processes are often regarded as loss
channels for an optical emitter1 because they are inherently
difficult to access experimentally. Recently, it has been shown
that emitters, such as fluorophores and nitrogen-vacancy
centres in diamond, can exhibit a strong non-radiative energy
transfer to graphene2–6. So far, the energy of the transferred
electronic excitations has been considered to be lost within the
electron bath of the graphene. Here we demonstrate that the
transferred excitations can be read out by detecting corresponding
currents with a picosecond time resolution7,8. We detect
electronically the spin of nitrogen-vacancy centres in diamond
and control the non-radiative transfer to graphene by electron
spin resonance. Our results open the avenue for incorporating
nitrogen-vacancy centres into ultrafast electronic circuits and
for harvesting non-radiative transfer processes electronically. |
