Summary: Negative lattice expansion-induced upconversion luminescence (UCL) thermal enhancement has been used to solve the thermal quenching problem of lanthanide ions and combined with traditional fluorescence intensity ratio technology for temperature sensing. Transparent glass ceramics of Na2MoO4:Yb3+, Er3+ were fabricated with linear negative thermal expansion, resulting in thermal enhancement of UCL. By combining the UCL characteristics of positive thermal expansion tellurite glass matrix and negative thermal expansion Na2MoO4:Yb3+, Er3+ nanoparticles, a novel glass ceramic temperature sensor with high sensitivity was developed. The potential of Na2MoO4:Yb3+, Er3+ transparent glass ceramics as a new generation of temperature sensors was demonstrated through excellent repeatability in cycle measurements.

Summary: Tertiary diethylpyridylphosphine was synthesized by reaction of pyridylphosphine with bromoethane in suberbasic medium. The reaction of phosphine with copper(I) iodide formed a copper(I) coordination polymer with an intermediate structure containing a copper-halide core. The obtained coordination polymer exhibited green and red emissions, and depolymerization resulted in the formation of a complex with the octahedral structure of the copper-halide core. The coordination polymer can serve as a sensor or detector for overheating processes that need to be maintained at temperatures below 138 degrees C.

Summary: In recent years, contactless thermal sensing has made significant progress due to the rapid development of luminescence thermometry. However, there is still room for improvement in the thermometric performances of these sensors. Most optical thermometers rely on a single temperature-sensitive luminescence parameter, but multiparametric readouts could enhance the reliability and broaden the working range of temperature measurements.

Summary: Fluorescent isocoumarin-fused cycloalkynes have been developed, which react in SPAAC and give fluorescent triazoles regardless of the azide nature. The introduction of a pi-acceptor group at the C6 position of the isocoumarin ring converts the non-fluorescent cycloalkyne/triazole pair to its fluorescent counterpart. The design of the fluorescent cycloalkyne/triazole pairs is based on theoretical studies of the deactivation mechanism and electron density redistribution.

Summary: Luminescent, heterometallic terbium(III)-lutetium(III) terephthalate metal-organic frameworks (MOFs) were synthesized using two methods: synthesis from diluted and concentrated solutions. The synthesized samples showed different crystalline phases depending on the concentration of Tb3+. The compounds corresponding to the Ln(2)bdc(3) crystalline phase demonstrated significantly higher photoluminescence quantum yields (PLQY) compared to other phases due to the absence of quenching from water molecules. One of the synthesized materials, (Tb0.1Lu0.9)(2)bdc(3)center dot 1.4H(2)O, showed a high PLQY of 95%, making it one of the most efficient Tb-based MOFs.

Summary: Luminescent NaYF4:Sm3+ nano- and microcrystalline materials co-doped with La3+, Gd3+, and Lu3+ ions were synthesized using the hydrothermal method. The synthesis process involved the use of rare earth chlorides as precursors and citric acid as a stabilizing agent. The synthesized materials exhibited a beta-NaYF4 crystalline phase, except for those with high La3+ content which formed LaF3. Particle size was significantly affected by the type and content of doping REE. Excitation at 400 nm resulted in distinct emission peaks in the visible spectrum due to transitions of the Sm3+ ion. Increasing the Sm(III) content led to concentration quenching, with an optimum concentration of 2%. Co-doping with non-luminescent La3+, Gd3+, and Lu3+ ions increased the emission intensity, explained by the viewpoint of Sm3+ local symmetry.

Summary: Luminescence thermometry offers remote temperature sensing with high spatial and temporal resolution. Several strategies have been explored to maximize the performance of these thermal sensors, including the use of multiple temperature-sensitive parameters. In this study, luminescence thermometry based on single parameter monitoring (LIR, spectral line position, and bandwidth) was compared with multiparametric sensing based on principal component analysis. The results showed that multiparametric thermometry outperformed the classical single parameter approach, offering potential for further enhancement of the thermometric performances of luminescence thermometers through data calibration.

The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
