“…According to the abovementioned analysis, each antibiotic can characteristically tune the energy transfer efficiency of ligand-to-metal energy transfer or modulate the energy allocation between analytes and the sensor [39]. Based on these interesting features, a reasonable 3D decoded map for different antibiotics can be fabricated by utilizing I 614 /I 590 , I 545 /I 490 , and I Ln or I L (I Ln equals to the sum of intensities at 617 and 545 nm; I L equals to the maximum intensity ranged from 425 to 475 nm) as the x-, y-, and z-axis, respectively.…”

“…In 2017, the double-selective detection of Ag + and Mn 2+ ions in water through the luminescence-color-changing process of a white-light-emitting lanthanide coordination complex was reported in our previous work [22]. In 2018, Su et al successfully achieved luminescence decoding for a series of metal ions in solution and volatile organic compounds in vapor by using Ln-MOFs with red and green-light emission [39]. Although some progress has been made in this regard, the multi-selective luminescence sensing technology based on Ln-MOFs is unreported, meanwhile the cogent system analysis for sensing mechanisms is still a great barrier for the development of this type of sensor.…”

Developing multi-selective luminescence sensing technology to differentiate serial compounds is very important but challenging. White-light-emitting decoding sensing based on lanthanide metal-organic frameworks (Ln-MOFs) is a promising candidate for multi-selective luminescence sensing application. In this work, three isomorphic Ln-MOFs based on H3dcpcpt (3-(3,5-dicarboxylphenyl)-5-(4-carboxylphenl)-1H-1,2,4-triazole) ligand, exhibiting red, blue, and green emission, respectively, have been synthesized by solvothermal reactions. The isostructural mixed Eu/Gd/Tb-dcpcpt is fabricated via the in-situ doping of different Ln3+ ions into the host framework, which can emit white light upon the excitation at 320 nm. It is noteworthy that this white-light-emitting complex could serve as a convenient luminescent platform for distinguishing eight frequently-used antibiotics: five through luminescence-color-changing processes (tetracycline hydrochloride, yellow; nitrofurazone, orange; nitrofurantoin, orange; sulfadiazine, blue; carbamazepine, blue) and three through luminescence quenching processes (metronidazole, dimetridazole, and ornidazole). Moreover, a novel method, 3D decoding map, has been proposed to realize multi-selective luminescence sensing applications. This triple-readout map features unique characteristics on luminescence color and mechanism. The mechanism has been systematically interpreted on the basis of the structural analysis, energy transfer and allocation process, and peak fitting analysis for photoluminescence spectra. This approach presents a promising strategy to explore luminescent platforms capable of effectively sensing serial compounds.

“…Since lanthanide ions have similar ionic radii, it is possible to dope Ln‐MOFs to tune a desired emission color using solvothermal methods. [ 35,36 ] Yet, the precursor concentration of the metal ions is not necessarily maintained as desired in the product. In addition, the energy transfer between two lanthanide ions additionally affects the color of the light emitted by the MOF.…”

The prolific topic of development of solidstate lighting devices has focused over the last years on solid-state white light (SSWL) emitting materials, mainly due the long operation lifetime and excellent harvesting and saving energy. [1] Even today, incandescent and mercury-based fluorescent materials are employed as white-light sources due to their superior warm-white light impression. Moreover, the fabrication of environmentally safe white light-emitting diode (LEDs) with a "warm-white" impression remains still a challenge. Many of the "white" organic light-emitting diode/ LED materials cover only part of the visible spectrum and lack the required efficacy of 150-200 lm W −1 for white-light performance. [2] For this reason, the design of a new generation of SSWL materials is of continuous interest in materials science, especially in areas such as full-color flat-panel electroluminescent displays for mobile devices, optical telecommunications, lighting, and backlighting for liquid-crystals displays. [3] Besides, high-quality white-light performance requires the Commission International de l'Eclairage (CIE) x,y coordinates 0.333, 0.333, with a correlated color temperature (CCT) into the 2500-6500 K, and color rendering index above 80 which are standard requirements for lighting applications. [4] One of the explored strategies to obtain white light is by combining red, green, and blue (RGB) sources to cover the visible region (400-700 nm) in the electromagnetic spectrum. [5] Also, metal-organic frameworks (MOFs) have been the focus of interest due to their potential applications in gas storage/ separation , [6] catalysis, [7] optics, [8] magnetism, [9] sensing, [10] and biomedicine. [4,11,12] Due to a permanent porosity, structural diversity, functionalization capabilities and then, tunable luminescence, MOF possess interesting properties for the development of SSWL composites. In recent years, a large number of luminescent MOFs have been reported for this purpose. [5,13-24] Moreover, for uses in nanotechnology, it is mandatory that MOFs are anchored on solid substrates, being particularly evident in the case of optoelectronic applications. [25,26] According to specialized reviews such as those from Wöll group, [27] it is distinguishable the surface-supported metal-organic frameworks (SURMOFs) devices, fabricated using layer-by-layer (LbL) A new set of Ln-MOF (lanthanide-metal-organic framework) thin films, known as Ln-SURMOFs (surface-supported MOFs), is fabricated with a layer-by-layer, in order to generate solid-state white-lighting devices. A three-component approach is carried out for a rational combination of red, green, and blue (RGB) emitting Eu 3+ , Tb 3+ , and Gd 3+ containing layers in order to achieve white-light emission. The Ln-SURMOFs are fully characterized by powder X-ray diffraction, infrared reflection-absorption spectroscopy, scanning electron microscopy, and photoluminescence spectroscopy (excitationemission and chromaticity determination according to Commission International de l'Eclairage, C...

“…The 5 D 0 level of Eu 3+ competes with the AT process by restraining or blocking the EnT from the ligand to the Ln 3+ ions. [ 55 ] Accordingly, the emission of the Eu 3+ is quenched. Based on the preceding reasons, Li et al recently examined the DET and FRET processes between the organic ligand tetramethylammonium and styrene (quencher); here, the suppression of the EnT from the ligand to Tb 3+ gives rise to the luminescence quenching effect.…”

Photonic functional materials with designable and tunable energy transfer (EnT) processes have become increasingly popular as they significantly broaden the landscape of currently available luminescent materials. Metal–organic frameworks (MOFs), which are constructed from organic ligands and metal ions/clusters, possess highly ordered networks and tunable luminescent properties that make them excellent platforms for exploring EnT mechanisms and designing directional EnT processes. Although the EnT processes in MOFs have been extensively studied, the intricacies of the mechanisms between multiple emitting centers are still relatively unexplored. Thus, the rational design of tunable luminescent materials is quite arduous without a comprehensive understanding of these underlying mechanisms. In this review, the basic theories behind MOFs is systematically introduced from the perspective of the inherent EnT processes. The use of MOFs as ideal platforms for studying EnT processes and developing an efficient engineering strategy for enhancing luminescence and facilitating novel optical behaviors is highlighted. In addition, applications utilizing EnT in MOFs are emphasized, and the future prospects for the development of this technology are discussed.
