Strong coupling detected in the photoluminescence of J-aggregate/plasmon hybrid systems

Autor: D. Melnikau, Yury P. Rakovich, Mikolaj K. Schmidt, Marek Grzelczak, Ana Sánchez-Iglesias, Diana Savateeva, Luis M. Liz-Marzán, Ruben Esteban, Javier Aizpurua

Publikováno v: 2016 Progress in Electromagnetic Research Symposium (PIERS).

The interaction between the excitonic J-band of J-aggregate molecules and localized plasmonic resonances supported by metallic structures can be large enough to reach the regime of strong coupling, giving rise to two hybridized modes [1, 2]. The new

Publikováno v: 2015 17th International Conference on Transparent Optical Networks (ICTON).

In this work we demonstrate the possibility to achieve efficient anti-Stokes photoluminescence emission and Raman scattering from semiconductor quantum dots deposited on spherical microcavity using excitation below the absorption edge of quantum dots

Publikováno v: 2015 17th International Conference on Transparent Optical Networks (ICTON).

We present our recent results on the development and characterization of hybrid sytems consisting of plasmonic nanostructures and organic dye molecules in a J-aggregate state. The measured spectra exhibit a strongly suppressed signal at wavelengths w
