Learning Objectives

Optical and optoelectronic materials have a technological impact in modern life. They include a large selection of materials, developed through an interdisciplinary approach. It can be distinguished two groups of optical materials: molecular materials and bulk materials which, in turn, can be classified in relation to their application in the optical/optoelectronic field. In this course will be presented and discussed the main families of optical materials, in relation to their optical properties, through the study of their crystal and electronic structure. Particular attention will be devoted to their design, synthesis and characterization, in order to optimize their properties and apply them in optoelectronic devices.

In addition, in the frame of the so-called Dublin Descriptors, this Course helps attain the following cross-disciplinary competences:
