Query: Exciton-plasmon Coupling and Electromagnetically Induced Transparency in
  Monolayer Semiconductors Hybridized with Ag Nanoparticles   Hybrid systems of excitons strongly coupled to localized surface plasmons
supported by metallic nanoparticles define a new approach to control
light-matter interactions. Here, we report exciton-plasmon coupling in
two-dimensional (2D) semiconductors, such as MoS2 and WS2, hybridized with
silver nanoparticles. Prominent photoluminescence enhancement in monolayer MoS2
was observed with localized surface plasmon resonance (LSPR) tuned to the
exciton resonance. By tuning the excitation energy, the contributions from near
field enhancement and radiative emission rate enhancement via Purcell effect
were resolved. Strong coherent dipole-dipole coupling between excitons and LSPR
in resonant condition manifests as an electromagnetically induced transparency
window in the extinction spectra of the localized surface plasmon. In this
strong coupling regime a new quasi-particle, known as a plexciton, is expected
to exhibit distinct properties, which exist in neither of the original
particles. Our results demonstrate that 2D semiconductors hybridized with
plasmonic structures not only hold great promise in the applications of
energy-harvesting and light-emitting devices, but also provide an attractive
platform for fundamental investigations of exciton-plasmon interactions in the
strong coupling regime.
