Ionic conductivity of and Raman spectroscopy investigation in binary oxosalts (1  x)AgPO _{3} xAg _{2}SO _{4} glasses
Abstract
(1  x)AgPO _{3} xAg _{2}SO _{4} homogeneous glasses obtained by quenching of a melt of the two salts are pure ionic Ag ^{+} conductors. The RT conductivity is increased from 2.5 × 10 ^{7} to 4 × 10 ^{6} (Ω cm) ^{1} when the ratio of Ag _{2}SO _{4} is increased from 0 to 0.3. Raman spectroscopy shows that no modifications of the (PO _{3}) ^{∞} chain skeleton occur by adding Ag _{2}SO _{4}. The lowfrequency Raman band lying at about 55 cm ^{1} is quantitatively correlated to Ag ^{+} oscillations, the hopping distance decreasing from 3.0 to 2.7 Å if a jump process between regular Ag ^{+} sites is considered.
