Optical diagnostic techniques of Smart Materials, Nanostructured Composite Materials

Optical diagnostic techniques of Smart Materials, Nanostructured Composite Materials

Description of the activity

The activities are focalized on nanotechnologies and photonic materials and devices, on polymer-based nano systems and organic-inorganic hybrid of metallic metamaterials, in addition to optical techniques and spectroscopy to study the optical properties of materials, and to characterize devices. Spectroscopic techniques are essential tools for high sensitivity and accuracy characterizations in many sectors with high technological content (integrated optics, biotechnology, non-linear optics, quantum optics, micro- and opto-electronics, homeland-security, sensors, imaging), but the rapid evolutions in these sectors require their continuous flexible adaptation to new materials, components and devices as well as the improvement of performance (eg increase in resolution). This is of particular relevance for reliable characterizations of micro- and nano- structures which are the basis of the aforementioned devices such as for example nanobiosensors and photonic and optoelectronic devices. In particular, Smart Materials and Nanostructured Composite Materials are optically characterized for the evaluation of far and near field properties by UV-Vis-NIR spectroscopy in transmission and reflection and dark field microscopy, Raman and SERS vibrational spectroscopy (@ 785nm and 1064nm), and with polarized optical microscopy; for structural / morphological evaluation using Scanning Electron Microscopy (SEM), atomic force microscopy (AFM) and Far Field diffraction analysis.
