Nanostructured superionic conductor LaF3doped by SrF2is obtained in the first time using the synthesis at the solution–gas interface. The product composition La1-xSrxF3-x(0 < x ≤ 0.16) was analyzed using SEM, FT-IR, XRD and EPM. It consists of nanosheets aggregated in microtubes. The SrF2content is varied from 2 mol% to 16 mol%. XRD analysis indicates tysonite crystal structure, which is still preserved up to 1000 K. NMR diffusometry has shown a significant enhancement of the diffusion coefficient, which is at least one order of magnitude higher than for undoped nanosized LaF3and about 3 orders of magnitude higher than for bulk LaF3at temperatures around 800 K.
