摘要：
The electrical properties of Tb4O7-bismuth titanate (Bi3.3Tb0.6Ti3O12) prepared by a conventional ceramic technique have been investigated. At applied d.c. field below 200V/mm, the current-voltage curve of Tb-doped sample exhibits a simple ohmic behavior. The impedance spectrum of Tb-doped sample indicates that consist of semiconducting grain and moderately insulating grain boundary regions. XRD, SEM and EPMA analyses reveal crystalline phase characterized by a Bi-layered perovskite structure of Bi4Ti3O12 and the distribution of every element is uniform. Tb-doped sample exhibit randomly oriented and plate-like morphology.
