Obiettivi formativi

The aim of the course is to provide in depth knowledge on various classes of nanomaterials that will constitute the main ingredient of future nanotechnologies. For each materials class, the synthesis approaches and the physical mechanisms underpinning their functionality will be studies discussed in detail with particular focus on size-related processes, such as quantum and dielectric confinement.

Applications of nanomaterials in various technological fields will be considered and their functioning principles will be studied, highlighting promising strategies for their design and optimization.

Regulation aspects regarding health, safety and environmental aspects of nanotechnology will be discussed.


The following classes of nanomaterials will be discussed:

1. Metal clusters: Bottom-up and top-down synthesis approaches, surface functionalization, electronic structure and size effects. Optical properties and photophysical processes. APplication in optoelectronic devices, sensors and biologic imaging.

2. Plasmonic metal nanoparticles: basic principles of plasmonics in dielectric confined nanomaterials, dielectic confinement, plasmon resonance and size/environment effects. Optical properties vs. size and dimensionality. Coulomb blockade effect and the concept of charge quantization. Applications in thermotherapy and sensing.

3. Colloidal semiconductor nanocrystals: Synthesis and surface chemistry, density of states in 3D and in 2-0 dimensional systems, electronic properties, excitonic (fine) structure, size an shape effects. Heterostructures and wave function engineering. Detailed photophysics, Electric transport. Doping and magnetic properties. Applications in LASERS, LEDs, bioimaging and energy technologies.
