“…In the recent decades, metal-organic frameworks (MOFs) have drawn increasing research interest on account of their unique features in their structures, such as permanent porosity, tunable structures, functions, and so on [ 5 , 6 , 7 , 8 ]. The potential applications of MOFs include but not limit to catalysis [ 9 , 10 , 11 ], sensing [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ], optics [ 21 , 22 , 23 , 24 , 25 ], gas storage and separation [ 26 , 27 , 28 , 29 ], bio-imaging, and drug delivery [ 30 , 31 , 32 , 33 ]. In particular, lanthanide metal-organic frameworks (Ln-MOFs), displaying bright luminescence with large Stokes shifts, high quantum yields, and long lifetimes, are widely used as versatile materials in optics and sensing [ 34 ].…”
