We demonstrate efficient coupling between plasmons in a single silver nanowire and nanocrystals doped with rare earth ions, α-NaYF4:Er(3+)/Yb(3+). Plasmonic interaction results in a sevenfold increase of the up-converted emission of nanocrystals located in the vicinity of the nanowires as well as much faster luminescence decays. The enhancement of the emission can be precisely controlled by the polarization of the excitation laser and is significantly stronger for polarization parallel to the…

The purpose of this review is to introduce and present the concept of metallic nanowires as building-blocks of plasmonically active structures, and to demonstrate several key ideas that involve interactions between plAsmon excitations and electronic states in surrounding molecules or other emitters.

Unidirectional broadband light emission from supported plasmonic nanowires.
TLDR
It is shown that single crystal silver nanowires supported on a dielectric interface behave similar to broadband unidirectional antennas for visible light, which could pave the way for development of metal nanowire as subwavelength directors of light in solar, sensor, and spectroscopy applications.

This work investigated the angular radiation patterns from individual silver nanowires decorated with rare earth ion-doped nanocrystals to estimate the branching ratio into both emission channels and to determine the diameter-dependent surface plasmon quasi-momentum, important parameters of emitter-plasmon structures.
Spectral Modifications and Polarization Dependent Coupling in Tailored Assemblies of Quantum Dots and Plasmonic Nanowires

The data imply that the 2D degenerate emission dipole orientation of the QD can be forced to predominantly emit to one polarization component dictated by the nanowire modes.
Plasmon-enhanced energy transfer for improved upconversion of infrared radiation in doped-lanthanide nanocrystals.
TLDR
This work utilizes resonant surface plasmon polaritons (SPP) waves to enhance UPL in doped-lanthanide nanocrystals and indicates that SPP waves not only enhance the electromagnetic field, and hence weak Purcell effect, but also increase the rate of resonant energy transfer from Yb( 3+) to Er(3+) ions by 6 fold.

Propagation lengths and group velocities of plasmons in chemically synthesized gold and silver nanowires.
TLDR
The measured propagation characteristics agree with numerical simulations, indicating that propagation in these wires is dominated by the material properties of the metals, with additional losses due to scattering from roughness or grain boundaries providing at most a minor contribution.
