In this work, the effect of acceptor of La³⁺‐sublattice and donor of In³⁺‐sublattice doping on the local structure of proton conductor BaLaInO₄ with block‐layered Ruddlesden–Popper structure was investigated. It was showed that both types of doping led to appearance of new kinds of the defects (oxygen vacancy and oxygen interstitial) and to the decrease in the tilting angles of [InO₆] octahedra due to the expansion of unit cell in the ab direction. The formation of a less distorted structure provided facilitated oxygen‐ionic and protonic transport and increased ionic conductivity.

掺杂对基于BaLaInO4的新型块状质子导体局部结构的影响

在这项工作中，研究了La ^3+-亚晶格的受体和In ^3+-亚晶格掺杂的供体对质子导体BaLaInO ₄具有块层Ruddlesden-Popper结构的局部结构的影响。结果表明，两种掺杂都会导致新的缺陷的出现（氧空位和氧间隙），并且由于晶胞在ab方向上的膨胀而导致[InO ₆ ]八面体的倾斜角减小。较少扭曲的结构的形成促进了氧离子和质子的传输，并增加了离子电导率。
