Contents
Methods and materials for obtaining photon emission from a nanomaterial subjected to external stimuli.
Relationship between physico-chemical properties and dimensionality of materials in modulating the radiative response.
Selection criteria for nanomaterials that allow reflection, transmission, propagation or amplification of electromagnetic radiation.
Reference texts
Teaching material recommended and / or made available by the teacher
Educational objectives
Regularly following the course regularly and successfully, the student will acquire:
- knowledge of the principles that determine the radiative behaviour of organic or inorganic nanomaterials;
- ability to rationalize the optical phenomena and being able to describe them, using the models acquired;
- ability to use a technical-scientific language appropriate to the problems dealt with.
Prerequisites
In order to be able to understand the contents and follow the course successfully, the student should have acquired the basic knowledge relating to:
- Maxwell's equations
- Quantum basis of the interaction between radiation and matter.
Teaching methods
The course consists of class lectures (for a total of 6 CFUs) on all subjects of the course using video devices.

Learning verification modality
The evaluation is conducted by an oral exam, which consists of a discussion lasting about 40-45 minutes aimed at ascertaining the level of knowledge and understanding achieved by students on the theoretical and methodological implications mentioned in the program.
The oral exam will also test the communication skills of the student to make use of the proper scientific language and the ability to apply theoretical concepts to practical experiments.
Extended program
The course aims to give the basic concepts of the interaction between nanostructured materials and electromagnetic radiation to rationalize the processes of propagation, absorption, emission and concentration of light based on the properties of the materials and their composition / structure. The program of the course is structured as follows:

- Review of the laws of radiation propagation in a homogeneous medium
- Effect of interfaces on the propagation of light.

- PROPAGATION OF RADIATION IN MEDIA WITH FINITE AND RESTRICTED GEOMETRY:
- construction of wave guides
- construction of light radiation concentrators - solar concentrators
-
- PROCESSES OF DISSIPATION IN MEDIA WITH FINISHED AND RESTRICTED GEOMETRY:
- spontaneous emission processes
- emission with spatially controlled patterns - luminescent solar concentrators
- stimulated emission processes - Qdots-Laser
- energy transfer processes and efficiencies in finite and nanometric geometries

- RADIATION AMPLIFICATION PROCESSES ON NANOMETRIC SCALE:
- Nano-plasmonic effect.

- TECHNOLOGICAL APPLICATIONS: description and discussion of numerous examples of use of the processes and phenomena treated, in the technological field in relation to the fields of communications, optical devices, sensors, bio-medicine optical circuits, etc ...
