Abstract

A Tm³⁺- Ho³⁺-codoped single crystal of monoclinic BaY₂F₈ has been characterized by means of high resolution FTIR spectroscopy in the wave number range 2000 - 24000 cm^-1 and in the temperature range 9 - 300 K. The energy level schemes of the two lanthanide ions as determined by the optical absorption spectra is presented, analyzed, and fitted within a single ion Hamiltonian model. The very small energy separation (about 0.6 - 1.6 cm^-1) measured between the first and second sublevels of the ground state manifolds for both the ions is in line with the theoretical predictions. The impurity-phonon coupling is put into evidence by the thermally induced line shift and broadening, and by the detection of vibronic replicas of a few lines.
