An important result of research on mixed-lanthanide metal鈥搊rganic frameworks (M鈥睱nMOFs) is the realization of highly sensitive ratiometric luminescent thermometers. Here, we report the design and synthesis of the new M鈥睱nMOF Tb_0.80Eu_0.20BPDA with high relative sensitivity in the physiological temperature regime (298鈥?18 K). The emission intensity and luminescence lifetime were investigated and compared to those of existing materials. It was found that the temperature-dependent luminescence properties of Tb_0.80Eu_0.20BPDA are strongly associated with the distribution of the energy levels of the ligand. Such a property can be useful in the design of highly sensitive M鈥睱nMOF thermometers.
