Electrical mobility of silver ion in Ag2O-B2O3-P2O5-TeO2 glasses
Original language description
The effect of adding TeO2 into (100-x)[0.5Ag2O?0.1B2O3?0.4P2O5]?xTeO2, with 0?80 mol% TeO2 glass on the structural changes and electrical properties has been investigated. DSC and thermodilatomery were used to study their thermal behavior, structure wasstudied by Raman spectroscopy and electrical properties have been studied over a wide temperature and frequency range by impedance spectroscopy. The addition of the third glass former, TeO2, to the glass network causes the structural transformation fromTeO3 (tp) to TeO4 (tbp) which contributes to the changes in conductivity. The glasses with low TeO2 content show only a slow decrease in dc conductivity with addition of TeO2 due to the increase of the number of non-bridging oxygens, which increases themobility of Ag+ ions. The steep decrease in conductivity for glasses containing more than 40 mol% TeO2 is a result of decrease of the Ag2O content and stronger cross-linkage in glass network through the formation of more Te-eqOax-Te bonds
