A mixed lanthanide complex was synthesized hydrothermally with two kinds of organic ligands, adenine and biphenyl‐4,4′‐dicarboxylic acid, and is formulated as Ad/Tb 0.999 Eu 0.001 /BPDC (Ad = adeninate, BPDC = biphenyl‐4,4′‐dicarboxylate). The photophysical properties, especially the fluorescent sensing properties, have been studied in detail and compared to those of Tb 0.999 Eu 0.001 /BPDC, with a single ligand. It can be used as a ratiometric luminescent thermometer on the basis of the energy transfer from Tb 3+ to Eu 3+ , whose color will change from green–yellow to red from 100 K to 300 K.
