Plasmonic lattices for controlling light-matter interaction.

Light-matter interaction can be controlled by means of resonant nanostructures. Bravais plasmonic lattices sustaining collective modes can be used to modify absorption and fluoresce of coupled emitters. Multipolar modes in achiral lattices enable engineering an enhanced near field chiroptical response. Non-Bravais lattices, such as the honeycomb one, possess an extra degree of freedom associated with the relative position of the constitutive sublattices. This is directly related to the relative phase of the modes of each sublattice and thus permits tailoring the optical response of the array.

Exciton-polariton in a dye-doped metal-insulator-metal structure

Aniket Patra1,2, Vincenzo Caligiuri2, Roman Krahne1, Antonio De Luca2

1Italy Institute of Technology, Italy; 2University of Calabria, Italy

We experimentally and theoretically demonstrate how, by changing the density of the excitons in an organic dye inside the cavity, one can tune the light-matter interaction in Metal-Insulator -Metal (MIM) system. Furthermore, we theoretically study the light-matter interaction in a double cavity MIM system, using the same organic dye, in which the strong light-matter signature was observed.

Tunable and Highly Ordered Array of Au Nano-Holes: preparation, characterization, and functional application

Maria Grazia Manera, Adriano Colombelli, Daniela Lospinoso, Roberto Rella

CNR - IMM, Italy

The realization of periodic plasmonic nanostructures featuring macroscopic scale and easily controllable size and lattice spacing is a challenging achievement for low-cost nanofabrication tools. In this work, a periodic array of metal nanostructures have been prepared on large-area by exploiting modified nano-sphere lithography (NSL) fabrication technique. A valuable ability is to couple the versatility offered by NSL with post-processing tools for the properly engineering of plasmonic nanoparticles.

Listening to metal nanoparticles super-aggregates by photoacoustics

Roberto Li Voti1, Grigore Leahu1, Concita Sibilia1, Roberto Matassa2, Giuseppe Familiari2, Sara Cerra3, Tommaso Alberto Salamone3, Ilaria Fratoddi3

1Department of Basic and Applied Sciences for Engineering (SBAI), Sapienza University of Rome, Via A. Scarpa 14, 00161 Rome Italy.; 2Department of Anatomical, Histological, Forensic and Orthopedic Sciences, Section of Human Anatomy, Sapienza University of Rome, Via A. Borelli 50, 00161, Rome, Italy.; 3Department of Chemistry, Sapienza University of Rome, P.le A. Moro 5, 00185 Rome, Italy.

Photoacoustic spectroscopy revealed to be a robust and non-destructive technique for determining self-assembled nanostructures. The use of a straightforward approach based on photoacoustic detection allows to listen to both the absorption and scattering phenomena generated by nanoparticle suspensions. Photoacoustic results are compared with dynamic light scattering and local transmission electron microscopy measurements, allowing to obtain a well-defined interpretation of super-aggregates. This innovative morpho-optical approach opens new perspectives for advanced biomedical and structural applications.
