Abstract

Oscillation strengths, emission and excitation spectra and decay times of Tm3+ and Er3+ in germanite glasses were measured. The results were compared with the data obtained previously in borate and phosphate glasses. The role of glass phonons on the transition probabilities, half-width of emission bands and the Stokes shift is discussed. Also, the influence of the cavity and the site symmetry in which the rare earth is situated on transition probabilities is discussed. Bands in the emission spectrum of Er3+, absent in the borate and phosphate, are detected in the germanite glasses. Probabilities of relaxation from 1D21G4 levels of Tm3+ in various glass hosts are calculated.
