Welcome to the Optical Spectroscopies on Plasmonic and Semiconductor Nanostructures Group
The main research lines of our group pertain to the Optical Spectroscopies on Plasmon Metal Nanostructures. Our aim is to contribute to the advance of knowledge through fundamental multidisciplinary research in the field of surface-enhanced optical spectroscopies (SERS, SEF, SEIR) on metal nanostructures supporting plasmon resonances, and, through theorical models, to the understanding of the electromagnetic processes involved. In particular, the following specific objectives will be pursued:
Experimental Objetives:
Surface-enhanced Optical spectroscopy on new metal nanostructures (nanoshells, trimer/dimer nanoantennas, nanostars, modified electrodes, etc.) that spectroscopy sensitivity and or/substrate fabrication improve.
Modification of the chemical properties of nanoparticle interfaces by functionalization in, order to fabricate nanosensors. Applications of this nanosensor devices to the analysis of polluted waters and drugs.
Spectroscopic characterization of molecules of interest in Cultural Heritage: ancient and new artificial building materials, pigments and binding systems.
Implement Drug/Biomolecule spectroscopic recognition schemes and applications to antitumoral drugs and radical scavengers with special effect in human aging processes.
Theoretical Objetives:
Theoretical research of the electrodynamic response of a variety of metallic nanostructures, isolated or in planar arrays (metasurfaces), with special emphasis on the impact of the plasmon and magnetic dipolar resonances on the mechanisms of: Fano resonances and bound states in the continuum, and enhancements of the Raman and the fluorescent emission of neighboring molecules.
Theoretical Nanophotonics, more in detail we research on topological photonics, whose key feature is the presence of surface states immune to disorder and impurities. We study these unusual properties in nanophotonic systems with a plethora of new applications and insights into physics. We aim to control the propagation of light at the nanoscale level and "spin-momentum-locked". All these concepts are in principle completely unrelated to photonics and, definitely, new physics are expected to emerge with promising applications, especially the connection with photonic circuits with spin polarization modes and quantum optical devices.
Condensed matter theory, we are interested in novel light-matter interaction problems where unusual phenomena take place.
