摘要：

We have determined NMR linewidths and nuclear spin relaxation rates for F-19, Li-7, and Na-23 nuclei. and electrical conductivity in ZrF4-based fluoride glasses as a function of temperature. The results indicate that both Li and F are mobile in the glass containing 20 mole% LiF, whereas only F is mobile in glasses containing NaF (up to 30 mole%) or no alkali ions. Finally we compare and discuss the activation energies for the various parameters.
