An important result of research on mixed-lanthanide metal-organic frameworks (M'LnMOFs) is the realization of highly sensitive ratiometric luminescent thermometers. Here, we report the design and synthesis of the new M'LnMOF Tb0.80Eu0.20BPDA with high relative sensitivity in the physiological temperature regime (298-318 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 Tb0.80Eu0.20BPDA 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'LnMOF thermometers.
混合镧系金属有机框架（M'LnMOFs）研究的一个重要成果是实现了高灵敏度的比率发光温度计。在此，我们报告了新型M'LnMOF Tb0.80Eu0.20BPDA的设计与合成，其在生理温度范围（298 - 318 K）内具有高相对灵敏度。研究了其发射强度和发光寿命，并与现有材料进行了比较。发现Tb0.80Eu0.20BPDA的温度依赖发光特性与配体能级分布密切相关。这种特性在高灵敏度M'LnMOF温度计的设计中可能会很有用。
