Abstract The present work describes the effect of acceptor and donor doping on the state of protons in block-layered proton conductors based on BaLaInO4. It was proved that the increase of the dopant concentration (both Ba2+ and Ti4+) leads to the increase of the amount of water uptake and at the same time to the decrease in the contribution of protons, involved in the strong H-bonds. The main factor determined the increase of concentration of protonic species is not the nature of appeared oxygen defects (oxygen vacancy or oxygen interstitial), but the increase in the unit cell volume during doping.

受主和施主掺杂对基于 BaLaInO4 的块状层状结构中质子状态的影响

摘要 目前的工作描述了受主和施主掺杂对基于 BaLaInO4 的块状层状质子导体中质子状态的影响。已证明掺杂剂浓度（Ba2+和Ti4+）的增加导致吸水量的增加，同时导致参与强氢键的质子的贡献减少。决定质子物种浓度增加的主要因素不是出现的氧缺陷（氧空位或氧间隙）的性质，而是掺杂过程中晶胞体积的增加。
