History

The Laboratory "Spectroscopy of crystals" was founded in 1987 by M. Iliev, V. Hadzhiev (Faculty of Physics at Sofia University) and I. Vergilov (Faculty of Geology and Geography at Sofia University), after agreement between the Department of General Physics of Faculty of Physics and the Department of Lithology and Petrography of Faculty of Geology and Geography for equipment integration. The aim was to provide a modern facilities for research and training in Raman and fluorescence spectroscopy.
Initially, the laboratory was equipped with:
The foundation of the laboratory coincides with the discovery of a new class of materials - high-temperature superconductors. The study of these and related materials by Raman spectroscopy becomes the main scientific area of research for the laboratory, although other materials have been studied and other experimental methods have been used. Initially the research on this topic was funded by the Science Committee and later by the Commission of the European Communities (under contract CIPA-CT93-0032). In the period 1991-1997, four doctoral theses and several diploma papers were prepared and defended in the laboratory.

Currently the laboratory research is highly diversified and includes a wide range of materials such as:
