“…In recent years, the development of lanthanide luminescent fluorescent probes for guest molecule (e.g., anions, cations, biomolecules) recognition has become an emerging field [ 24 , 25 , 26 , 27 ]. Our group has been devoted to the preparation of lanthanide hybrid materials and sensing applications, and the rapid development for the achievement of specific lanthanide sensors has been reported [ 28 , 29 , 30 ]. Previously, we found a ClO − highly selective Europium sensor based on an oxime isomerization reaction for the first time [ 31 ].…”

The presence of nitrite (NO2−) in water and food leads to serious problems in public health and the environment. Therefore, it is important to develop a rapid and efficient method for the selective detection of NO2−. In this work, the synthesis and characterization of magnetic Fe3O4@SiO2-TbDPA nanoprobe have been carried out. The Fe3O4@SiO2-TbDPA aqueous solution exhibits a strong green emission. Due to the addition of various concentrations of NO2− (0–100 μM), the fluorescence intensity has been suppressed. The nanoprobe Fe3O4@SiO2-TbDPA exhibits excellent selectivity and sensitivity toward NO2− ions. Excellent linearity is obtained in the range of 5–80 μM with a detection limit of 1.03 μM. Furthermore, the presence of magnetic Fe3O4 nanoparticles in Fe3O4@SiO2-TbDPA nanospheres will also facilitate the effective separation of Fe3O4@SiO2-TbDPA from the aqueous solution. Our proposed strategy is expected to fabricate an organic-inorganic hybrid magnetic nanomaterial and can be used as an efficient sensor. It has been shown that this new strategy has numerous advantages, such as high stability, selectivity, and simplicity of operation. It demonstrates great potential for simple and convenient NO2− detection. It may expand to a variety of ranges in environmental monitoring and biomedical fields.

“…Myriad researches have been done in the sector of materials which show the property of luminescence. It has been noticed that the photophysical characteristics of luminescent materials are responsible for their possible usages in different fields like sensors, displays, and optical devices [1][2][3][4][5][6][7][8][9]. In 1942, Weissman has observed that upon irradiation with ultraviolet light source the organo-lanthanide complexes show superior luminescent intensity as compared to free lanthanide ion [10].…”

1,10-Phenanthroline-based luminescent materials play an important role as an excellent class of optoelectronic materials due to their remarkable and novel attributes for optoelectronic applications. There is an enormous demand of luminescent materials in many fields. The foremost objective of this paper is to synthesize fluorescent derivatives of 1,10-phenanthroline. The electronic effect of the substituents on the heteroaromatic ligand has been reviewed in solid state. These ligands were characterized by electrochemical study and spectroscopically. The value of energy band gap is estimated to be 3.0-4.5 eV for synthesized compounds. Photophysical features were analyzed through photoluminescence spectrometer, which indicates a strong impact of the substituents on the photoluminescent properties of the phenanthroline ligand. Upon excitation in ultraviolet region, intense broad band appeared in emission spectra of synthesized compounds lie in visible region which is further supported by CIE color coordinates. The detailed explanation about the geometry and frontier molecular orbitals calculation was carried out with the help of Avogadro and ORCA software.

“…Lanthanide hybrid materials nanofiber films exhibit the following advantages: (i) excellent luminescent performance; (ii) good mechanical strength and photo-/thermal stability; (iii) low cost and easy processability; (iv) easy to recycle and convenient to use. These excellent nanofiber films will open opportunities for further exploration for sensing applications. − For example, Zhou’s group prepared a polymeric-based ternary europium(III) complex system for monitoring HCl gas release in practical environment . Wang and co-workers synthesized a novel hybrid luminescent material by covalent attachment of 4-vinylpyridine-2,6-dicarboxylic acid to AC, and the as-prepared hybrid material exhibits good acid–base gas sensitive properties .…”

A ternary europium(III) coordination polymer, namely, [Eu(ctpy)(tta)2] n (1) (Hctpy = 4′-carboxy-2,2′:6′,2″-terpyridine and Htta = 2-thenoyltrifluoroacetone), was obtained and exhibits a 1D chain structure. 1-Eu emits intense red light, which can act as a luminescent dopant to be immobilized into polymers to prepare nanofiber films by an electrospinning technique. Subsequently, ternary europium-chain@polymer nanofiber films (1-Eu@PAN and 1-Eu@PMMA, PAN = polyacrylonitrile, PMMA = poly(methyl methacrylate)) as functional films have been successfully fabricated. These nanofiber films possess excellent mechanical strength and photo-/thermal stability, as well as emit luminous red light. The luminescent investigation indicates that the maximum intensity of the 5D0 → 7F2 transition of EuIII ion occurs in 1-Eu@PAN and 1-Eu@PMMA nanofiber films with 10 wt % 1-Eu loading. In addition, 10% 1-Eu@PAN nanofiber film can be used as a recyclable sensor for detecting Fe3+ ion in aqueous solution because 10% 1-Eu@PAN nanofiber film have good recyclability and selectivity. Electrospinning technique is an effective strategy to fabricate lanthanide coordination polymer-encapsulated polymer fiber films and to contribute to develop sensors.
