Preparation of transparent oxyfluoroborate glass-ceramics containing CaF2〈Eu〉 crystals

The glass-forming region in the CaF 2 -Bi 2 O 3 -B 2 O 3 system has been determined for the first time. We have prepared glasses of various compositions, investigated their physicochemical properties, and examined the effect of rare-earth (La, Nd, Eu, Dy, Er, Tm, Yb) doping on the crystallization be...

Description
Summary:The glass-forming region in the CaF 2 -Bi 2 O 3 -B 2 O 3 system has been determined for the first time. We have prepared glasses of various compositions, investigated their physicochemical properties, and examined the effect of rare-earth (La, Nd, Eu, Dy, Er, Tm, Yb) doping on the crystallization behavior of the glasses. Transparent glass-ceramics containing ∼40-nm Ca 1 − x Eu x F 2 and Ca 1 − x La x F 2 crystallites have been obtained. The luminescence properties of the glasses and glass-ceramics have been studied.
