Color tunable and white light emitting Tb3+ and Eu3+ doped lanthanide metal–organic framework materials

A Boiling‐Water‐Stable, Tunable White‐Emitting Metal–Organic Framework from Soft‐Imprint Synthesis

“…[13] Indeed, Tb 3 + readily forms an isostructural net (denoted as 2-Tb) under similar conditions, and bimetallic nets containing evenly mixed Eu/Tb ions at variable ratios (i.e., 2-Eu/Tb systems) can be readily accessed by adjustingt he metal ratios in the reaction mixture (e.g.,F igure 4g-i). As the red emission from the Eu 3 + ions complements the green from Tb 3 + (Figure 5a), the photoluminescence properties can be systematically tuned by the Eu/Tb ratio that is built into the host net (see also Figure 5b).…”

Observation of divergent La3+ ion dilute effect in two series of 3-D fluorescent lanthanide-MOFs-based molecular alloys RELa1−–EBTC (RE3+=Eu3+ or Tb3+; EBTC4−=1,1′-ethynebenzene-3,3′,5,5′-etracarboxylate)

“…With the use of different lanthanide ions and the judicious choice of the bridging ligands, the luminescence properties of the resulting MOFs may be modulated, even white light emitting materials are achievable in this way [21]. In addition, the lanthanide ions have similar ionic radii, charge, chemical behavior, etc, to lead to the coordination 3 compounds with different lanthanide ions being possible isomorphs.…”

“…Moreover, the series sharp bands within 362418 nm in the excitation spectra of Eu−EBTC and Eu x La 1-x −EBTC areIn the end, it needs to be mentioned that Rao et al[35] have reported a rational design strategy to construct white light emitting materials by doping isostructural Tb 3+12 and Eu 3+ into isostructural lanthanum metal-organic framework. In their work, as Tb 3+ /Eu 3+ doped into isostructural La−MOF, the corresponding emissions gradually increased with the doped amount of Tb 3+ /Eu 3+ from 0.1 % to 10 % molar percentage.However, their work mainly focused on generating white light emitting materials so they did not further investigate more doped molar percentage of Tb 3+ /Eu 3+ in La−MOF.…”

Syntheses, structures and tunable luminescence of lanthanide metal-organic frameworks based on azole-containing carboxylic acid ligand

“…Common approaches, such as dichromatic, tri-chromatic, and tetra-chromatic methods are often used to generate white light [13][14][15]. However, tri-chromatic white light emitting materials have recently been attracting much attention due to their excellent color rendering properties and color stability, as well as high efficiency [16][17][18][19].…”

“…Furthermore, isostructural mixed LnMOFs could be synthesized via in situ doping because of the comparability in the chemical reactivity and coordination behavior of the lanthanide ions. As a consequence, the color of the emitted light can be modulated by the constituent lanthanide ions and their relative concentrations [16][17][18][19].…”
