Graphene plasmonics

open access: yesNature Photonics, 2012
Two rich and vibrant fields of investigation, graphene physics and plasmonics, strongly overlap. Not only does graphene possess intrinsic plasmons that are tunable and adjustable, but a combination of graphene with noble-metal nanostructures promises a ...

Effective plasmonic enhancement of up-conversion photoluminescence from $$\alpha$$ -NaGdF4:Yb3+,Er3+ nanoparticles by gold dendrites [PDF]

open access: yesScientific Reports
The current paradigm of plasmon-enhanced up-conversion photoluminescence (PE-UCPL) lays in intimate coupling domains of noble metal and lanthanide-doped nanoparticles.

Plasmon–exciton polaritonic emission lifetime dynamics under strong coupling [PDF]

open access: yesNanophotonics
In this study, we investigate the contribution of resonant and non-resonant excitation conditions on the polariton decay dynamics of strongly coupled rhodamine 6G (R6G) and surface plasmon polariton (SPP).
