Near-field energy transfer using nanoemitters for optoelectronics

Effective utilization of excitation energy in nanoemitters requires control of exciton flow at the nanoscale. This can be readily achieved by exploiting near‐field nonradiative energy transfer mechanisms such as dipole‐dipole coupling (i.e., Förster resonance energy transfer) and simultaneous two‐wa...
