Photo of the studied glasses in a shape of discs with the thickness of about 2.5 mm. The black sample is the G6 glass sputtered with platinum electrodes for the ionic conductivity measurement.
(a) Raman spectra of the G1-G7 samples; (b) Raman spectra of the G4, G8-G10 samples.
Typical impedance curve with a high-frequency arc and a low-frequency tail of the G4 sample at 298 K.
Arrhenius plots of the G1-G7 samples. The straight lines correspond to the linear fits of the data.
The conductivity vs Ag content at different temperatures.
The real part of permittivity ε′ vs. frequency f presented in the log-log scale for the G1-G7 samples. The inset represents an example of d2 log ε′/d(log f)2 dependence on frequency for the G5 sample.
Compositions of the glass samples, the nominal, and real Ag atomic percentage.
Compositional dependence of the ionic conductivity σ 298K at ambient temperature, the activation energy E σ and the pre-exponential factor σ 0 obtained from the Arrhenius equation.
The parameters α(T) and ln A(T) obtained by fitting for the G1-G7 samples at different temperatures.
