Department of Solid State Engineering

Synopsis:

The practical course gives an overview of experimental methods used in optical spectroscopy for the study of photoluminescence, optical absorption and Raman scattering of solids. Attention is particularly paid to the description of block arrangement of experimental set-ups and methods for measurement of chosen characteristics of optical properties of solids, to the physical quantities used and to the techniques of processing, graphical representation, and interpretation of measured data. The general approaches described are illustrated in practice through measurements on model samples performed by students on appropriate equipment in the laboratory.
