Abstract: Luminescence data for Eu3+ and Gd3+ in fluoroindate glasses are compared to those of a fluorozirconate glass. Emission is observed from Eu3+ 5D(J) (J = 0, 1, 2 and 3) and Gd3+ P-6(7/2) excited-state levels and the results put in evidence Eu-Eu and Gd-Eu energy transfer processes. Vibronic bands related to a 320 cm-1 vibrational mode could be observed for Eu3+ luminescent transitions with DELTAJ = 0, 1 and 2 and also for the P-6(7/2) --> S-8(7/2) transition of Gd3+. Lanthanide ion site symmetry is closer to an inversion center in fluoroindate glasses than it is in fluorozirconate.
