摘要

A family of novel 2D-layered lanthanide germanates K ₃[Tb _xEu _1-xGe ₃O ₈(OH) ₂] (x = 1, 0.88, 0.67, 0; denoted as TbGeO-JU-87, Tb _0.88Eu _0.12GeO- JU-87, Tb _0.67Eu _0.33GeO-JU-87, and EuGeO-JU-87) were synthesized under mild hydrothermal conditions in a concentrated gel system. They are isostructural, as confirmed by the powder X-ray diffraction analysis. The single-crystal X-ray diffraction analysis of EuGeO-JU-87 reveals that it is a 2D-layered [EuGe ₃O ₈(OH) ₂] _n ^3n- anionic framework, which is built up from GeO ₄H/ GeO ₄ tetrahedra and EuO ₆ octahedra by sharing vertex O atoms. Charge neutrality is achieved by K ⁺ ions located in the free void space. Interestingly, photoluminescence studies show that Tb _0.88Eu _0.12GeO-JU-87 and Tb _0.67Eu _0.33GeO-JU-87 exhibit a high Tb ³⁺-to-Eu ³⁺ energy-transfer efficiency and the Tb _xEu _1-xGeO-JU-87 system displays tunable photoluminescent properties.
