| 英文摘要 | 0.35La(2)O(3)-0.65Nb(2)O(5) glasses were prepared by aerodynamic levitation method. The dielectric properties of the sample were investigated as a function of temperature (30-700 degrees C) in the frequency range from 100 Hz to 1 MHz. The glasses show a temperature and frequency-independent dielectric constant of 40 below 200 degrees C. A relaxor-like behavior was observed above 200 degrees C, which was found to be composed of two relaxations with the activation energy of 1.32 eV and 1.3 eV for the low- and high temperature relaxations, respectively. Impedance analysis reveals that the low-temperature relaxation is a conduction relaxation associated with hopping motion of oxygen ions and the high-temperature one is a Maxwell-Wagner relaxation associated with phase boundary. The relaxor-like behavior is attributed to the combining effect of both relaxations. (C) d2016 Elsevier Ltd. All rights reserved. |
