| Résumé |
|
The lanthanide metal-organic framework, La1.23Na0.30(1,3-BDC)2(H2O)·4H2O (1,3-BDC: 1,3-benzenedicarboxylate), has been for the first time synthesized under microwave-assisted hydrothermal conditions with a synthesis duration of 5 min. The substitution of La3+ by Eu3+ and Tb3+ was possible until a maximal content of 10%.mol and the investigation of luminescence properties reveals that emitting cations can be located in the chains formed by the LnO10 polyhedra but also into the polar channels proposed by the structure, where some La3+ crystallographic sites are also available. Finally, when codoped by Eu3+ and Tb3+, the materials exhibit thermometric properties in the cryogenic range with a maximal relative thermal sensitivity around 1% K−1 at 80 K.
