Mazzera, A. Baraldi, E. Buffagni, R. Capelletti, E. Beregi, I. Földvári, N. Magnani] Yttrium aluminium borate single crystals, doped with 1 and 4 mol% of Pr3+, were analyzed in the wave number range 500-25000cm−1 and temperature range 9-300K by means of high-resolution Fourier transform spectroscopy. In spite of the complex spectra, exhibiting broad and split lines, the energy level scheme was obtained for several excited manifolds. The careful analysis of the spectra as a function of the temperature allowed us to identify most of the sublevels of the ground manifold. The thermally induced line shift, well described by a single-phonon coupling model, could be exploited to provide information about the energy of the phonons involved. The orientation of the dielectric ellipsoid and of the dipole moments associated to a few transitions was also determined from linear dichroism measurements. The experimental data were fitted in the framework of the crystal-field theory, but the agreement was not satisfactory, as already reported for Pr3+ ion in other matrices. Additional discrepancies came from the dichroic spectra analysis and the line splitting, possibly associated to hyperfine interaction. Some causes which might be responsible for the difficulties encountered in the Pr3+ ion theoretical modelling are discussed. Springer-Verlag, 2011 Mazzera M.
