Evaluation of the morphology and chelating agent excess in the design of luminescent metalorganic framework of europium thenoyltrifluoroacetone

“…The energy transition involved in the emission of TTA: Eu 3+ obtained at an excitation wavelength of 254 nm starts with excitation of the S 0 to S 1 singlet, where the energy descends to a T1 state and passes to a characteristic energy state of Eu 3+ to follow its descent from 5 D 0 → 7 F j (j = 0,1, 2, and 3) radiatively, with its highest luminescence intensity at 612 nm. These results are similar at reported of the emission in the band of 530–630 nm which is a typical emission in Eu 3+ within of MOF.…”

“…7 F j (J = 0-2) transitions. The highest luminescence intensity is found in the 5 D 0 transition to 7 F 2 , which corresponds to the characteristic emission of the Eu 3+ ion.…”

“…There is a correlation between the coordination geometry and the dimensionality: size 1 Divisio ´n de Ciencias Ba ´sicas e Ingenierı ´a, Universidad Auto ´noma Metropolitana-Azcapotzalco, Col. Reynosa-Tamaulipas, Me ´xico or hardness of the metal center and electronic configuration affect the resulting topology of MOF. 2,3 Over the last years, MOFs have emerged as a new promising porous material in the areas of gas sorption and separation, 4 as platform for immobilizing molecular catalysts on conductive substrates, [5][6][7][8] water treatment, 9 storage, 10 antibacterial and antobiofilm 10 and light emitting diodes (LEDs). 11 Rare earth doped materials are very useful nowadays, because the characteristics that provide the lanthanides to the material can confer new applications as optoelectronics devices, fiber amplifiers, solid state laser, 12 solar cells, 13 and luminescence.…”
