Two isostructural lanthanide metal‐organic frameworks [ Ln ‐MOFs, Ln = Tb ( 1 ), Eu ( 8 )] containing oxalic acid ligand with green, red luminescence were solvothermally synthesized. A series of Eu/Tb mixed MOFs ( 2 – 7 ), (C 5 H 6 N) 2 [Eu x Tb 2– x (H 2 O) 2 (C 2 O 4 ) 4 ] · 2H 2 O, were designed and obtained, which displayed highly tunable luminescence color by adjusting the excitation wavelength. Complexes 1 – 8 were characterized by IR, elemental analysis, ICP, powder XRD, and TG measurements. The quantum yields of the complexes 1 – 8 range from 6.89 to 4.15 %, whereas the fluorescence lifetime of 1 – 8 varies between 1.12 and 0.87 ms. Therefore, with the increase of the molar ratio of Eu, the quantum yields and fluorescence lifetime of the complexes 1 – 8 gradually decrease.
