文摘

A luminescent mixed lanthanide metal鈥搊rganic framework approach has been realized to explore luminescent thermometers. The targeted self-referencing luminescent thermometer Eu_0.0069Tb_0.9931-DMBDC (DMBDC = 2, 5-dimethoxy-1, 4-benzenedicarboxylate) based on two emissions of Tb³⁺ at 545 nm and Eu³⁺ at 613 nm is not only more robust, reliable, and instantaneous but also has higher sensitivity than the parent MOF Tb-DMBDC based on one emission at a wide range from 10 to 300 K.
