Zusammenfassung
This Thesis includes the experimental results can be summarized by two objectives. First, develop an experimental work dedicated to design and development of new devices that allow for spectroscopic measurements under extreme conditions of pressure and temperature. Between all the productions highlights the Spectroscopic Characterization Microscope (ES2461015B2 patent). Second, to apply the techniques developed to scientific case. Notably, the interest in the correlation between the crystalline and electronic structure systems Co2+: CoF2, CoCl2 and KCoF3. Another compound has been GeCuO3 system that presents transitions Spin-Peierls type, a rich piezocroism and depends on the average hydrostatic pressure transmitter. Finally, thus its optoelectronic applications, LiNbO3: Tm3+ have investigated allowing test the operation of various techniques applied to the study of rare earth doped materials.
