Plasmon-enhanced energy transfer via nanostructures (Conference Presentation)

Paper Abstract

In this work, we have designed and fabricated an array of plasmonic nano-ellipse that interacts with different types of QEs in the visible range of wavelength. The proper geometry of our design provides such absorption-reflection properties which spectrally overlap with the emission spectrum of the QE. Alongside such spectral overlap, a thin layer of the dielectric layer between the plasmonic structures and a gain medium provides the possibility of spatial overlap. The interaction between the strong subwavelength localized field at the edges of the gold nano-ellipses and QEs, enhances Purcell factor towards the modification of the fluorescence and decay time of QEs. This approach allows enhanced emission from different emitters embedded in hybrid quantum systems. In this work, we study the energy transfer between the fluorescent dye molecules and CdSe/ZnS hydrophobic QDs with the array of plasmonic nano-ellipses.
