Fluorescence Profile of Calabrian Opuntia ficus-indica Cladodes Extract: a Promising Low-cost Material for Technological Applications
Antonio Ferraro, Sephora Kamwe Sighano, Roberto Caputo +3
The autofluorescence of calabrian Opuntia ficus-indica bioactive extract upon UV illumination is explored by fluorescence spectroscopy enabling to investigate the typology and dist…
Unlocking optical coupling tunability in epsilon-near-zero metamaterials through liquid crystal nanocavities
Giuseppe Emanuele Lio, Antonio Ferraro, Bruno Zappone +6
Epsilon-near-zero (ENZ) metamaterials represent a powerful toolkit for selectively transmitting and localizing light through cavity resonances, enabling the study of mesoscopic phe…
Tailoring of Plasmonic Functionalized Metastructures to Enhance Local Heating Release
Antonio Ferraro, Giuseppe Emanuele Lio, Abdelhamid Hmina +3
Plasmonic nanoheaters are reported that produce a significant local heating when excited by a 532 nm wavelength focussed laser beam. A significant temperature increase derives from…
Color Tuning by Spontaneous Propagation of Gap Surface Plasmons in Epsilon Near Zero Nano-Cavity
Giuseppe Emanuele Lio, Antonio Ferraro, Michele Giocondo +2
This work presents numerical and experimental results of plasmonic Metal-Insulator optical nano-cavities. The systems are composed of Silver as metal, polyvinylpyrrolidone or indiu…
