Electrochemical response of Nd3+ ions containing lithium borate glasses

The present investigation was to understand the electrical properties of 27.5 Li2O-(72.5-x) B2O3-x Nd2O3 with x=0.5, 1, 1.5 and 2 glasses. We analyzed the impedance data for a wide frequency range to get inside the conduction phenomenon. The conductivity of the glasses decreased due to the decrease in the mobility of mobile Li+ ions. This decrease was due to polymerization of glass network caused by the Nd3+ ions. Modulus formalism confirmed that the Li+ ions overcame the same barrier no matter whether it took part in the conduction process or relaxation process. Scaling of the electrochemical data showed that conduction process in the ion conducting glasses was composition dependent and not the temperature dependent.
