Summary: By utilizing a triazole-pyridine-containing ligand, two novel coordination polymers with varying Ag(I) cluster architectures have been successfully synthesized. Compound 1 features an isolated cluster, while compound 2 exhibits a 2D framework due to different coordination modes of the N-donor linker. Solid-state photoluminescence and luminescence lifetimes have been investigated for both compounds, showing potential for application as ratiometric fluorescence molecular thermometers, especially due to compound 1's wide temperature sensing range.

Summary: In this study, a K5GdLi2F10 compound doped with Tb3+ and Eu3+ was synthesized, and a strong coupling between terbium and europium was found. The energy transfer processes from terbium to europium mainly depend on fast migration, with the lifetime of D-5(4) multiplet in the presence of europium being shorter by about 30% compared to singly doped terbium compounds.

Summary: Luminous coarse-, micro- and nanocrystalline europium(III) terephthalate tetrahydrate metal-organic frameworks were synthesized using ultrasound-assisted wet-chemical method. The nanoparticles have an average size of about 8 +/- 2 nm, making them the smallest rare-earth-based MOF crystals known, emitting red light due to Eu3+ transitions. Additionally, Cu2+, Cr3+, and Fe3+ ions selectively quench the luminescence of nanocrystalline europium(III) terephthalate, showing potential for monitoring these ions in water.

Summary: In this study, a series of continuous, low-thickness lanthanide-MIL-103 SURMOFs were fabricated using a layer-by-layer (LbL) approach in the liquid-phase epitaxy process. These Ln-SURMOFs exhibit highly sensitive thermometers with optical readout, which can be observed with the naked eye. High transmittance is achieved by precisely controlling the film thickness and quality of these Ln-SURMOF thermometers. Moreover, the thermal sensitivity in the temperature regime above 120 K can be improved by controlling the energy transfer between Tb(III) and Eu(III) through a sophisticated supramolecular architecture, namely MOF-on-MOF heteroepitaxy.

Summary: A multifunctional lanthanide metal-organic framework Tb(cpioa) with a porous 3D network crystal structure was successfully synthesized by a facile hydrothermal method. The recognition capabilities of acetone, Fe3+, and Cr2O72- in water were specific and sensitive. The luminescence quenching mechanism was found to be complex, involving UV-vis absorption competition, weak interactions between ligands and analytes, and two dynamic transfer processes: fluorescence resonance energy transfer (FRET) and photo-induced electron transfer (PET).

Summary: There is a growing interest in finding alternatives to lanthanide ion (Ln(III))-based luminescence sensitizing chromophores for in vivo applications in optical biological windows. Transition metals (M) are considered as relevant candidates due to their high absorption rates and emission bands covering a wide range of visible to near-infrared spectrum. However, there has been limited research on the energy transfer (ET) processes between M and Ln(III) ions. In this study, a new model incorporating intramolecular energy transfer (IET) and phonon-assisted energy transfer was proposed to predict and explain the photophysical properties driven by the energy transfer between Ln(III) ions and transition metals.

Summary: The increasing demand for computing power has pushed current lithographic methods to their limits, hindering further shrinkage of silicon chips using top-down approaches. The recent chip shortage has highlighted the world's excessive reliance on silicon and emphasized the need for silicon-free computing technologies, preferably at the molecular level. This study demonstrates an all-photonic device based on the emission dynamics of Eu3+ and Tb3+ ions in a Eu3+/Tb3+ co-doped organic-inorganic di-ureasil hybrid, showcasing a temperature-reprogrammable shift from a low-pass filter to a high-pass filter and paving the way for molecular analogs of conventional circuit components.

Summary: Luminescent thermometry enables remote temperature detection and has great potential in future technological applications. We demonstrate for the first time that luminescence thermometry can be combined with a complementary temperature readout related to a different property. By taking advantage of the temperature dependence of magnetic and luminescence features in Single-Molecule Magnets (SMM), we develop original dual magneto-optical molecular thermometers that offer a 10-fold improvement in relative thermal sensitivity over the whole temperature range.

Summary: Glasses with tunable properties are versatile materials for optical technologies. To design new optical glasses, understanding the correlation between their chemical composition and physical properties is crucial. We demonstrate the feasibility of using fluoride phosphate glasses co-doped with Pr3+ and Yb3+ ions for temperature sensing. These glasses have high stability and act as luminescent thermometers without the need for recurring calibration. They exhibit competitive thermal sensitivity and uncertainty, making them promising for cost-effective and accurate temperature probes, advancing photonic technologies.

Summary: It is generally known that the emission intensity of trivalent lanthanide ions (Ln(3+)) increases on cooling, but recent studies have shown that the intensity of Eu3+ photoluminescence decreases on cooling. In this study, the mechanism underlying this anomalous behaviour was investigated using experimental and theoretical approaches. It was found that off-resonance excitation enhanced the Eu3+ emissions with increasing temperature, and the temperature dependence of the emission intensity could be tuned by varying the bandpass of the excitation source.

Summary: In this study, efficient ratiometric nanothermometers based on mesoporous stellate nanoparticles were synthesized and characterized. These nanothermometers exhibited temperature-dependent luminescence and high thermal stability, repeatability, and sensitivity in the range of 20-70°C. The modification of photoluminescence properties and the increase in Tb3+-to-Eu3+ energy transfer rate were rationalized by changes in coordination number and symmetry evolution.

Summary: A ratiometric thermometer based on a mixed Eu-Tb metal-organic framework is reported, which has a maximum relative thermal sensitivity of 16.1% K-1, making it one of the best-performing thermometers currently reported. The sensing mechanism of {[Tb2-xEux(H(2)Btec)(Btec)(H2O)(2)]& BULL;4H(2)O}(n) (Btec = 1,2,4,5 Benzenetetracarboxylic acid) has been attributed to a phonon-assisted energy migration between neighboring Tb3+ ions in the structure.

Summary: Choosing a suitable host matrix for temperature sensing in biomedical applications requires low cytotoxicity, easy synthesis, and the ability to be doped with light-emitting ions. Indium-based halide double perovskites, namely Cs2AgIn0.9Bi0.1Cl6, Cs2Ag0.6Na0.4InCl6, and Cs2Ag0.6Na0.4In0.9Bi0.1Cl6, were selected as host materials to develop lanthanide-based primary thermometers due to their low phonon energy and ease of synthesis. These perovskite samples demonstrated excellent thermal stability and were able to withstand temperatures as high as 500 degrees C. A temperature-dependent green emission of Er3+ was observed in the co-doped samples, exhibiting a relative thermal sensitivity of 1.3% K-1 and an uncertainty in temperature values of 0.3 K. Incorporating these perovskites into L2929 cells resulted in high cell viability, highlighting the advantages of using low-cytotoxicity materials for biological applications.
