Electrical properties of Agx(GeSe3)1-x (0≤x≤0.571) glasses were investigated by impedance spectra and EMF measurements. As the concentration of silver is increased the total electrical conductivity steeply increases from 10-14 S/cm to 10-3 S/cm at about x = 0.3. This rapid increase is chiefly due to an appearance of silver ion migration. Glass transition temperature showed a minimum at x = 0.33 above which a first sharp diffraction-peak in powder X-ray diffraction diminishes. This unusual transition supports a percolation hypothesis on photo-dissolution of silver in these glasses.
