| 英文摘要 | Bi1-x(Sr0.5Pb0.5)(x)FeO3 with x = 0.1 and 0.3 were synthesized by solid-state reaction method. The dielectric properties of the samples have been investigated in the temperature range from 100 to 300 degrees C. The colossal dielectric constant (CDC) behavior was observed in temperature range from 50 to 200 degrees C and frequency range from 10(2) Hz to 10(3) Hz. The CDC behavior is composed of two relaxation processes with the lower temperature relaxation being a dipolar relaxation caused by the hopping of oxygen vacancies and the higher temperature one being a Maxwell-Wagner relaxation caused by hopping oxygen vacancies blocked by grain boundaries. In the temperature range beyond 200 degrees C, a ferroelectric-phase-transition-induced dielectric anomaly with an extremely huge intensity over 10(6) was observed in both samples. (Sr, Pb) co-doping in the place of Bi significantly shift the Curie temperature towards a low temperature of 263 and 243 degrees C for the samples with x = 0.1 and 0.3, respectively. |
