1)        Synthesis of Carbon Dots                                                                                                           High-boiling
                                                                                                                                               solvents Hydrothermal
through ‘bottom-up’ approaches, consisting in selecting opportune precursor molecules (that meet
criteria of cost effectiveness and sustainability) and processing them at high temperatures and in
different conditions (controlling the atmosphere, the pressure, the presence of additives, …)*
          *Minervini,   G., et al., Materials 2020, 13 (17), 3716                                                          Small molecules                                   Carbon Dots

2)        Characterization of their properties
by integrating different investigation techniques, to determine their properties (shape,
structure, composition, optical properties). In particular, the use of fluorescence spectroscopy in
the range of UV-visible is considered essential to evaluate the optical performances of the CDs.

3)        Fabrication of advanced nanocomposites
through the integration of CDs in various types of solid matrices (polymeric, glass, ceramic, ...),
also in combination with other nanoparticles, with the aim to combine synergistically the
optical properties of the nanostructured materials with the mechanical and rheological
properties of the matrices

4)        Enhancement of their performances
especially to respond to crucial issues that criticality limit the use of CDs in some application fields. For example,
enhancement of the emission of the CDs based materials in the spectral region of the red/near-infrared (620-700 nm)
