PECULIARITIES OF THE DIFFUSION OF SILVER AND SODIUM-IONS IN PHOSPHATE-GLASSES WITH A HIGH CONTENT OF NA2O

The conductivity relaxation due to Na+ ions and the decay of radiation -induced centers controlled by Ag+ ion diffusion have been studied in phosphate glasses with a high content of Na2O. Both of the processes d isplay a nonexponential kinetic behavior and are satisfactorily descri bed by the Kohlrausch function. It has been demonstrated that on the m olecular level the Kohlrausch function should be interpreted as a sum of exponential decay functions with a distribution of relaxation times rather than the inherently nonexponential function.
