“…Enhancing the performance of materials by tuning the crystal structure is essential for developing new multifunctional semiconductor materials. For example, rare‐earth solid‐solution materials with unique crystal structure can be obtained by adjusting the ratio of solid‐solution components, which is an interesting way to develop new multifunctional semiconductor materials 1–3 . Variable valence rare‐earth elements, due to the shielding effect of their outer electrons and thermally activated conduction properties, 4 are highly attractive for various optical and temperature sensor devices.…”

As new multifunctional semiconductor materials, solid‐solution ceramics demonstrate great potential in the field of electronic and optoelectronic devices. CaEuNbMoO8 ceramic is the solid solution of EuNbO4 and CaMoO4, but how to synergistically regulate its transmission of electricity and light still remains challenging. Herein, the structure modulations by adjusting the ratio of EuNbO4 and CaMoO4 and the changes in electrical transport and photoluminescence (PL) properties have been investigated. Meanwhile, the asymmetric ratio (5D0–7F2/5D0–7F1) further determines the symmetry variation of the local microstructure with the solid‐solution ratio of EuNbO4. The correspondence between the structure and phase transition of EuNbO4 ceramics at high temperature is investigated, and it is found that the point symmetry changes from C2h to C4h, and the activation energy changes significantly with increasing temperature. This work provides a solution for the synergistic optimization of PL and conductivity of solid‐solution ceramics by modulating the symmetry of the crystal structure.

High Cs+ ion conductivity was successfully realized in solids at temperatures below 250 °C by doping Cs–bis(trifluoromethanesulfonyl) amide (CsTFSA) into cubic rare earth oxides of R2O3. Among the (1 − x)R2O3–xCsTFSA solids prepared, a 0.75Gd2O3–0.25CsTFSA solid showed the highest Cs+ ion conductivity of 3.4 × 10−2 S cm−1 at 250 °C, which is the highest value yet reported for a solid Cs+ ion conductor.
