Abstract
The effect of the Ag2O on the conductivity of vanadium tellurite glasses ha s been studied by using the impedance spectroscopy in a wide range of tempe rature. The obtained results confirm the existence of a transition from a t ypically electronic (polaronic) conductive regime when the molar fraction ( X) of Ag2O is equal to 0, to a ionic conductive regime when X tends to 1. T his transition is characterized by a deep minimum in the electrical conduct ivity of about 3 orders of magnitude. (C) 2000 Elsevier Science BN. All rig hts reserved.
