Abstract
Fluoride glasses (especially when entirely free of oxide or phosphate) show remarkably weak multi-phonon de-excitation. The two main types are barium zirconium fluoride glasses invented at U. Rennes, and zinc gallium fluoride studied at U. LeMans. An approximate rule is that luminescence can be detected of a J-level in a fluoride glass, if the closest lower J-level is at least 2000 cm** minus **1 below.
