| Research Abstract |
In this study, we succeeded in preparation of Cs^+-embedded (inner-modified) PB nanocrystals in their crystal lattice spaces and surface-modified PB nanocrystals by K^+, Na^+, and NH4^+ using their unsaturated coordination sites. Ion conductivities of the inner-and surface-modified PB nanocrystals were 10 or 100 times increased in the solid state (pellet), compared to that of the original PB. In higher relative humidity conditions, the ion conductivities were elevated, suggesting significant contribution of the proton transportation. Both hydration structures of interface among the PB nanocrystals and their inner lattice spaces play an important role in the solid-state ion conductivity mechanism.
