Abstract

High resolution (0.04 cm-1) absorption spectra of Dy 3+-doped YAl3(BO3)4 (YAB) single crystals were measured by Fourier transform spectroscopy in the spectral (2000-23 000 cm-1) and temperature (9-300 K) ranges. Samples with nominal 1 and 4% Dy/Y molar ratios were studied. Dy3+ transitions from the 6H15/2 ground state to the 6H 13/2, 6H11/2, 6H9/2+ 6F11/2, 6H7/2+ 6F 9/2, 6H5/2, 6F7/2, 6F5/2, 6F3/2, and 4F 9/2 excited states were analysed. A small (∼3.3 cm-1) splitting between the first two sublevels of the 6H15/2 ground manifold was detected. The experimentally determined energy levels were fitted with a single-ion Hamiltonian and the crystal-field parameters were obtained. The same procedure was applied to analyse the previously published high resolution spectra of YAB:Er3+, leading to a reliable unified picture for the two dopants.
