The metal–organic frameworks (MOFs) have received great scientific attention
during the last decade. MOFs are built metal cations or cluster-like
arrangements linked via the coordination of organic ligands, granting them a
host of properties, including porosity. Particularly a feature of a number MOFs
that has recently come to greater attention is photoluminescence, the emission
of light upon photoexcitation, combining this property with the versatility of
MOFs is an attractive research goal, with potential applications such as chemical,
biological, radiation detection, medical imaging, and electro-optical devices [1,
2]. In this work, we report on a fast, simple and facile synthesis of three
luminescent MOFs. They were prepared based on terbium as the metallic
lanthanide, and 1,4-benzenedicarboxylate (BDC), benzene-1,3,5-tricarboxylate
(BTC) and 2,5-thiophedicarboxylate (TDC) as organic ligands. These luminescent
compounds have showed a high intensity green light emission at 487, 546, 586
and 621 nm, associated with inter electronic energy state trasitions of the Tb 3+
ion, 5 D 4 à 7 F J (J=6, 5, 4, 3) respectively. The MOFs were synthesized by microwave
method and characterized by elemental analysis, X-ray powder diffraction
patterns (PXRD), thermogravimetric analysis (TGA), infrared spectroscopy and
scanning electron microscopy (SEM).
