The dynamics of the F sub-system in InF3–BaF2–BiF3 glasses were characterized by means of 19F nuclear magnetic resonance spectroscopy, impedance spectroscopy and electrical conductivity measurements. The results demonstrated that increasing the BiF3 content improved the dynamic characteristics of the F sub-system and increased the conductivity of the glasses.
