ItalianoOur research is focusing on the study of surfaces and interfaces at the nanoscale. To this aim, we use colloidal inorganic semiconductor nanocrystals as (soluble) frameworks and apply to these the synthetic and spectroscopic methods derived from coordination chemistry. Particular emphasis is put on the surface chemistry of colloidal nanocrystals as a mean to subtly tune their optical and electronic properties and the inter-nanocrystal non-covalent bonding interactions. Such interactions are exploited to self-assemble the colloidal nanocrystals into ordered supra-structures, up to the macroscopic size scale of optoelectronic and photonic devices. We, therefore, ultimately pursue a thorough description towards control of the ubiquitous interfaces in nanocrystal-based solids over multiple length scales.
