| Abstract: | The electrochemical behavior of the LaF3 : Eu2+|  interface (Me = Sm, Ce, Gd, V, Ag) is studied using stripping voltammetry. Current–voltage curves for cells Ag, AgCl|KCl and KF|LaF3 : Eu2+|Sm (or Ce) may be viewed as background curves for analyzing solid-phase reactions with other metallic electrodes. The substrate material is found to affect properties of interfaces LaF3 : Eu2+/Gd (or V), which are characterized either by solid-phase reactions involving the fluoride ion of a solid electrolyte or by reactions involving oxygen. Regularities, obtained for silver in contact with LaF3 : Eu2+, link electrochemical signals of the reaction of the silver fluoride formation with the contact area. |
