N2 - The fluorine mobility in single crystals of the anion-deficient solid solution La1-xSrxF3-x (x=0, 0.001, 0.003, 0.01, 0.03, 0.05 or 0.16) with the tysonite structure has been studied in the temperature range of 130-520 K by 19F NMR. Different modes of ionic motion were identified and the leading mechanism of ionic diffusion has been suggested. The influences of temperature and fluorine vacancy concentration on the ionic mobility in tysonite have been investigated. In all crystals, fluorine diffusion begins in the F1 sublattice. On increase in the temperature, ionic exchange between the F1 and F2,3 sublattices becomes observable. Addition of small amounts of Sr (x<0.003) significantly increases the ionic mobility between the sublattices. For 0.0031 sublattice. At these doping concentrations the influence of large clusters seems to play a significant role.
