A weak mixed mobile ion effect in vanadium–tellurite oxide glass modified by silver and lithium cations

The effect of the partial replacement of lithium oxide by silver oxide in a glassy vanadium–molybdenum–tellurite oxides matrix is analyzed by means of impedance spectroscopy. We find that a weak mixed mobile ion effect (MMIE) is due to the different kind of modifications silver and lithium oxides in...

Zusammenfassung:	The effect of the partial replacement of lithium oxide by silver oxide in a glassy vanadium–molybdenum–tellurite oxides matrix is analyzed by means of impedance spectroscopy. We find that a weak mixed mobile ion effect (MMIE) is due to the different kind of modifications silver and lithium oxides induce in the glass of formula 0.7[ x Ag 2O (1 − x) Li 2O] 0.3[0.5 V 2O 5 0.5 MoO 3] 2 TeO 2.
