“…This result indicated that rare earth Tb(III) ions successfully coordinated with carboxyl acid ligands. Moreover, the Δν ðν as -ν s Þ values of all complexes were approximately 123 cm -1 , which is less than 200 cm -1 , indicating that the Tb(III) ion and ligands were in the form of chelate bidentate coordination [30,32]. There were two absorption peaks from the ethylenic bond at 3075 cm -1 and 1644 cm -1 , which were assigned to ν =CH and ν C=C , respectively.…”

“…Most rare earth complexes select aromatic cyclic carboxylic acids as ligands because they contain conjugate double bonds and rigid plane structures that have good absorption in the ultraviolet region [28][29][30][31]. Nevertheless, this study selected unsaturated fatty acids called 10-Undecenoic acids to coordinate with terbium ions that can emit a bright pure green light.…”

A UV-cured composite containing a rare earth complex was prepared for this study. First, the photoluminescent terbium complex was synthesized with a long-chain unsaturated fatty acid (10-Undecenoic acid) by a solution precipitation method, resulting in the 10-UA-Tb(III) complex. Its structure was proven by FTIR, elemental analysis, XRD, and TGA. The results indicated that the organic acid ligand successfully coordinated with the Tb 3+ ion and that the complex had a chelate bidentate structure. The emission spectrum of the 10-UA-Tb(III) complex indicated that the complex can emit a bright green light with the unique luminescence of the Tb 3+ ion. Furthermore, the luminescence properties of complexes with different ratios of Tb 3+ and ligand were studied, and the ratio of Tb 3+ and the ligand had an obvious impact on the luminescence intensity of the 10-UA-Tb(III) complex. Subsequently, the prepared rare earth complex was doped into a UV-cured coating in different proportions to obtain a UV-cured composite. The morphology of the rare earth UV-cured composite was observed by SEM. The images showed that the rare earth complex was dispersed uniformly in the polymer matrix. Moreover, the composites could emit fluorescence. Additionally, it has good thermal stability and compatibility with the resin. Therefore, these composites should have potential applications in UV curable materials, such as luminescence coatings.

“…As shown in the inset of Figure 5(a), 5 D 0 → 7 F 1 transition at 592 nm of Eu 3+ ions followed magnetic dipole rules and the corresponding fluorescence intensity did not change significantly with the variation of x due to its independence of Eu 3+ ions chemical environment. 33,34 As a contrast, 5 D 0 → 7 F 2 transition at 616 nm, obeying the electric dipole mechanism, was very sensitive to the chemical environment of Eu 3+ ions and the properties of ligands, and its intensity was directly proportional to the Judd Ofelt Ω 2 parameter. 34…”

In this work, a novel kind of carboxyl-containing poly(ether ether ketone) (PEEK-COOH) was successfully synthesized and carefully characterized. Based on PEEK-COOH as macromolecular ligands, a series of luminescent rare earth polymer complexes (PEEKn-Eux-Tb1-x) were prepared and made into flexible films. The effects of the ratio of carboxyl ligand to rare earth ions on fluorescence intensity of complexes were studied and discussed. When the molar ratio was 6:1, the fluorescence emission intensity reached a maximum. Furthermore, the relative emission intensity of Tb3+ and Eu3+ binary system depended on their ratio and the intensity of fluorescence emission peak exhibited continuous change. Because of this, the color of the prepared fluorescent films could range from bright green to fire red, and each color has high purity. The fluorescence lifetime of complexes ranged from 0.428 to 0.511 ms. Absolute quantum yield of PEEK-Eu0.4-Tb0.6 was 8.4%. Beside this, these fluorescence films exhibited a high thermal stability with 5 wt. % in the range of 240–250°C, and its tensile strength was about 28 MPa. In addition, PEEKn-Eux-Tb1-x films possessed good optical transparency. All the interesting results suggested the potential application of the luminescent rare earth polymer complexes in display devices and photo-electronic devices.

“…Thus, one approach to enhance the luminescence intensity of lanthanide ions is to employ some heteroatom-containing (e.g., O and/or N) organic compounds as ligands, which can transfer energy from their triplet state to Ln 3+ ions, providing the Ln complex with brighter emission than the ligand-free Ln 3+ ions. It is widely referred as the antenna effect (AE). , Therefore, tremendous efforts have been dedicated to explore the AE-dependent lanthanide(III) luminescent materials, such as rare earth inorganic materials, , coordination polymers, metal–organic frameworks (MOFs), , and so on. Specifically, the triphenylamine (TPA) derivative with strong UV absorption is employed as an energy receiver, and the luminescence of Eu 3+ is sensitized through energy transfer .…”

Lanthanide(III)-based luminescent materials have attracted great research interests due to their unique optical, electronic, and chemical characteristics. Up to now, how to extend these materials into large, broad application fields is still a great challenging task. In this contribution, we are intended to present a simple but facile strategy to enhance the luminescence from lanthanide ions and impart lanthanide(III)-based luminescent materials with more applicable properties, leading to meet the requirements from different purposes, such as being used as highly emissive powders, hydrogels, films, and sensitive probes under external stimuli. Herein, a water soluble, blue color emissive, temperature sensitive, and film-processable copolymer (Poly-ligand) was designed and synthesized. Upon complexing with Eu3+ and Tb3+ ions, the red color-emitting Poly-ligand-Eu and green color-emitting Poly-ligand-Tb were produced. After finely tuning the ratios between them, a standard white color emitting Poly-ligand-Eu1:Tb4 (CIE = 0.33 and 0.33) was obtained. Furthermore, the resulted materials not only possessed the emissive luminescent property but also inherited functions from the copolymer of Poly-ligand. Thus, these lanthanide(III)-based materials were used for fingerprint imaging, luminescent soft matters formation, colorful organic light-emitting diode device fabrication, and acid/alkali vapors detection.
