DIELECTRIC SPECTROSCOPY OF IONIC GLASSES OF THE SYSTEM CuI-CuBr-Cu2O-P2O5

We have used dielectric relaxation spectroscopy to measure frequency and temperature dependence of complex dielectric functions epsilon*(omega), epsilon*(T) of ion conductive glasses of the system CuI-CuBr-Cu2O-P2O5. The observation, analysis and interpretation of the temperature and frequency dependences of real and imaginary part of the dielectric permittivities can reflect the basic features of the relaxation and transport processes of the mobile ions. The experimental results are analyzed, discussed and compared with both acoustic and conductivity spectra measurements.
