The spin-coating technique was used to produce composite films consisting of PMMA polymer doped with anisometric complexes of Eu(III) and Tb(III). It was found that an increase in the content of Tb3+ complexes intensifies emission of both ions due to the intermolecular energy transfer from the Tb(III) complex to the Eu(III) complex, which results in the increase in the relative luminescence quantum yield of Eu(III) ion by 36%. The temperature sensitivity of the film luminescence intensity and lifetime in the range of 296–363 K was investigated. The maximum relative sensitivity of the films reaches 5.44% × K−1 and exceeds that of all known lanthanide-containing thermal sensors designed for measuring physiological temperatures. In combination with changing luminescence color, such a sensitivity makes these films promising colorimetric thermal sensors for in situ temperature measurements.

In order to expand the application of bio‐based polycarbonate in optical components, a series of PICC/ rare earth ion complex fluorescent composites were prepared by using PICC as macromolecular ligand and Eu3+ and Tb3+ as rare earth luminescence centers. The coordination system between rare earth ions and PICC was investigated by FTIR, DSC and TGA. At the same time, by adjusting the ratio of Eu3+ and Tb3+, the PICC/ rare earth ion composite with adjustable fluorescence color was obtained. At the same time, the thermal, mechanical and optical properties of a series of PICC/ rare earth ion fluorescent films with different ratios were tested. A transparent fluorescent composite material with excellent mechanical properties and tunable fluorescent colors has been prepared.This article is protected by copyright. All rights reserved.

“…Lanthanide compounds, particularly europium(III) complexes, are commonly utilized as luminescent additives in multifunctional materials [2,[30][31][32][33][34][35][36][37][38]. The low emission efficiency of lanthanide ions which is related to poor light absorption can be omitted by a complex formation in which the organic ligand plays the role of an "antenna".…”

A series of homogeneous hybrid BPA.DA-NVP@Eu2L3 materials were obtained through an in situ approach where the luminescent dopant was formed at the molecular level with different contents (0.1; 0.2; 0.5; 1; and 2% by weight). A Europium(III) complex (Eu2L3) with quinoline-2,4-dicarboxylic acid was applied as a luminescence additive while a polymer matrix consisted of a combination of bisphenol A diacrylate (BPA.DA) and N-vinylpyrrolidone (NVP) monomers. Synthesis steps and the final materials were monitored by NMR and Fourier transform infrared spectroscopy (FTIR). The emission, excitation spectra, lifetime, and quantum yield measurements were applied for the determination of the photophysical characteristics. The thermal and mechanical properties of the obtained materials were tested via thermal analysis methods (TG/DTG/DSC and TG-FTIR) in air and nitrogen atmospheres, dynamic mechanical analysis (DMA), and hardness and bending measurements. Generally, even a small addition of the metal complex component causes changes in the thermal, mechanical, and luminescent properties. Hybrid materials with a greater europium complex content are characterized by a lower stiffness and hardness while the heterogeneity and the flexibility of the samples increase. A very small amount of an Eu2L3 admixture (0.1% wt.) in a hybrid material causes an emission in the red spectral range and the luminescence intensity was reached for the BPA-DA-NVP@1%Eu2L3 material. These materials may be potentially used in chemical sensing, security systems, and protective coatings against UV.
