Investigations on the Optical Spectra of Transition Elements in Single Crystals of High Symmetry

摘要

The theoretical and experimental aspects of the optical spectra of the S state ions Mn2+ and Fe3+ in cubic fields were investigated. The optical spectrum and the ground state splitting of V3+ in Al2O3 was studied. The spectrum of Pr3+ in the single crystal of CaWO4 was measured in absorption and fluorescence. The line shape of the Pr3+ lines was investigated as a function of the temperature. (Author)
