In our work with aim of artificially designing new type of cation conductor, intercalation of various guest elements into van der Waals spaces of layer structured compounds has been investigated. The present work has studied doubly intercalation of iodine as bridging anions and silver as conducting cations into Sr-doped Bi_2O_3 (SBO) with van der Waals spaces, and characterized resultant intercalation compounds. Until now, the following results have been obtained in our investigations.・ The doubly intercalation of iodine and silver into SBO can take place in the following stepwise process the iodine elements are first intercalated into the SBO around 440K and then the silver elements are intercalated in the I-intercalated SBO around 570K.・ The doubly intercalation brings about a large expansion around 1 nm in the c axis of host structure. It has been suggested from calculations for one-dimensional electron distribution that the iodine and silver intercalated are located within the van der Waals spaces of host structure.・ The amounts of guest elements intercalated are controllable with the amount of silver added to starting mixture.・ The Ag intercalation makes high conductivities for the new intercalation compounds thus synthesized. The above results indicate that the enhanced electrical properties are due to migration of Ag intercalated.

在我们以人工设计新型阳离子导体为目的的工作中，研究了各种客体元素在层状结构化合物的范德华空间中的嵌入，目前的工作研究了碘作为桥接阴离子和银作为导电阳离子的双重嵌入。具有范德华空间的 Sr 掺杂 Bi_2O_3 (SBO) 以及所得插层化合物的特征 到目前为止，我们的研究已获得以下结果。碘和银双重嵌入SBO可以按照以下逐步过程进行：碘元素首先在440K左右嵌入SBO中，然后银元素在570K左右嵌入I嵌入SBO中。从一维电子分布的计算可以看出，碘和银的插层在主体结构的 c 轴上发生了约 1 nm 的大膨胀。位于主体结构的范德华空间内。·插入的客体元素的量可以通过添加到起始混合物中的银的量来控制。·Ag的插入使得由此合成的新插层化合物具有高电导率。电性能的增强是由于插层银的迁移所致。
