The tunability of surface resonance frequency in plasmonic metal nanostructures via size and shape control, when coupled with the absorption frequency of various organic and inorganic excitons, provides a unique nonlinear response. Achieving these nonlinear responses, such as formation of a transparency window, using different organic and inorganic excitons increases future applicability of the technology, which includes sensors, light-harvesting systems, and other optical devices. These transparency windows have been reported in silver nanoplatelet-J-aggregate dye systems and have been observed in silver nanoplatelet-inorganic quantum dot systems. In this work, the coherent plasmon-exciton coupling of silver nanoplatelets with a J-aggregate dye and cadmium telluride/selenide quantum dots is explored. Direct and near direct overlap of absorption spectra of plasmons and excitons are examined to determine Rabi splitting energies and the strength of nonlinear absorption impacts.
