缺陷工程被应用于诱导氧化物结构和介电行为的可控变化。采用标准固相法制备了变价态络合离子（Nb, Zn）（x+） （x = 2, 3, 4, 5）修饰的SrTiO3陶瓷。系统地研究了（Nb, Zn）共掺SrTiO3陶瓷的相结构、微观结构、缺陷结构和介电性能。在受体共掺杂中，M2陶瓷（x = 2）表现出极低的介电损耗(
Defect engineering is applied to induce controllable changes in structures and dielectric behaviors in oxides. SrTiO3 ceramics modified by complex ions (Nb, Zn)(x+) (x = 2, 3, 4 and 5) with variable valence states are prepared by standard solid state method. Phase structures, microstructures, defect structures and dielectric properties of the (Nb, Zn) co-doped SrTiO3 ceramics have been systematically investigated. In acceptor co- doping, M2 ceramics (x = 2) exhibits extremely low dielectric loss (
