Abstract

A series of molecular alloy based on rare earth (RE) oxalate (Eu_xGd_1−x)₂(C₂O₄)₃(H₂O)₆ (abbr. as Eu_xGd_1−x-OX, x = 0.1–0.9) were synthesized using hydrothermal reaction. The PXRD profiles of Eu_xGd_1−x-OX (x = 0.1–0.9) match well with the simulated pattern calculated from the single crystal data of Nd₂(C₂O₄)₃(H₂O)₆ reported previously, indicating that the as-prepared molecular alloys are isomorphic to Nd₂(C₂O₄)₃(H₂O)₆. EDS and ICP measurements proved the coexistence of Eu and Gd elements in this series of alloys. The photoluminescent (PL) behaviors of Eu_xGd_1−x-OX (x = 0.1–0.9) as well as the physical mixed RE oxalates solids were carefully studied. It is found that the PL intensity of Eu_xGd_1−x-OX with small amount of Gd³⁺ ion is obviously enhanced due to reducing dipole–dipole, dipole–quadrupole or quadrupole–quadrupole interaction between emitters of Eu³⁺ ions as well as energy transfer from Gd³⁺ ion to Eu³⁺ ion. This study demonstrates that forming molecular alloy by introducing proper ion is an efficient strategy to get improved PL materials.
