Abstract

The intensity parameters of holmium in sodium, barium and zinc tellurite glasses were obtained from the absorption spectra. Using these parameters and the matrix elements of Ho3+, transition probabilities and branching ratios from the excited states (5F4, 5S2), 5F5, 5I4, 5I5 and 5I6 were calculated. Quantum efficiencies for the (5F4, 5S2) state were obtained and the multiphonon transition rates calculated at room temperature. Non-radiative multiphonon relaxations were obtained from the (5F4, 5S2) level. The relaxation increased in the order of zinc, barium, sodium, and is assumed to be dependent on the local site symmetry of Ho3+ in glass.
