The key role of the composition and structural features in fluoride ion conductivity in tysonite Ce1−xSrxF3−x solid solutionsElectronic supplementary information (ESI) available: Cell parameters, F-(Ce,Sr) distances and additional 19F MAS NMR spectra of Ce1−xSrxF3−x solid solutions.

Pure tysonite-type Ce 1− x Sr x F 3− x solid solutions for 0 ≤ x < 0.15 were prepared by a solid-state route at 900 °C. The cell parameters follow Vegard's laws for 0 ≤ x ≤ 0.10 and the solubility limit is identified (0.10 < x limit < 0.15). For 0 ≤ x ≤ 0.05, the F2-(Ce,Sr) and F3-(Ce,...
