This work aims to study light-matter interaction at the nanoscale by integrating emitters with plasmonic structures. Our
proposed structure consists of metallic nanoprisms in the center of ring diffraction gratings. Surface plasmon polaritons
(SPPs) are generated by the ring grating which propagate and get focused on the nanoprism tip forming an intense
electromagnetic hotspot in the region. FDTD numerical simulations are done to calculate the optimized angle of
incidence needed for SPP excitation by the ring grating. Sample fabrication and optical characterization methods are
presented to study the coupling between generated SPPs and CdSe quantum dots placed in the center. FDTD simulations
as well as experimental observations are done to study the electromagnetic hotspot at the tip of the ring gratingnanoprism
structure. This work will be extended further to include the coupling between SPPs and emitters placed in the
hotspot which leads to their photoluminescence and lifetime enhancement.
