Summary: A series of SrGa12-xAlxO19:0.5%Cr3+(x = 0, 2, 4, and 6) solid-solution phosphors were successfully synthesized through Al3+ alloying strategy. The introduction of Al3+ can regulate the crystal field and symmetry, achieving the synchronous tuning of E-2 and T-4(2) energy levels and extending the temperature sensing range. Among all samples, SrGa6Al6O19:0.5%Cr3+ showed the widest temperature measuring range from 130 K to 423 K with Sa of 0.0066 K-1 and Sr of 1% K-1@130 K. This work provides a feasible way to extend the temperature sensing range for transition metal-doped LIR-mode thermometers.

Summary: A temperature measurement method based on the luminescence intensity ratio of emission line at 698 nm and emission bands at 713 and 721 nm is proposed, which has high relative sensitivity and low temperature resolution. As the temperature increases, the emission line at 698 nm increases by 84-fold while the emission bands at 713 and 721 nm show the opposite declining trend. This method provides high relative sensitivity of 13.09% K-1 and low temperature resolution of 0.032 K.

Summary: Remote temperature and pressure monitoring provides opportunities to explore the luminescence properties of compounds under extreme conditions. In this study, double perovskite Gd2ZnTiO6 phosphors doped with Mn4+ were developed as bifunctional sensors for temperature and pressure. The optimized doping concentration of Mn4+ was found to achieve the highest emission intensity, and the concentration quenching mechanism was determined to be dipole-dipole interaction. The synthesized phosphors exhibited high internal and external quantum efficiencies, and demonstrated good thermal and pressure sensing properties.

Summary: This study overcomes the sensitivity limit of Boltzmann's thermometers by utilizing seven thermalized Dy3+ excited states in the Lu1.5Y1.5Al5O12 host. By extending the conventional two-thermalized level Boltzmann-type luminescence intensity ratio (LIR) to seven thermalized levels, the approach provides higher energy differences and enables a five times larger sensitivity than the conventional LIR.

Summary: Introducing smaller Mg2+ ions to replace Ca2+ site in the BaLaCaSbO6 matrix leads to a significant enhancement in luminescence intensity, red-shift, and luminescence lifetime. These modulations are mainly attributed to the strengthen pressure on the local structure, superior lattice rigidity, and suppression of non-radiative transition after the substitution of smaller Mg2+. The effective lifetime-based luminescence thermometry is achieved due to thermal quenching behavior of Mn4+ ions in the matrix.

Summary: This study demonstrated that temperature-driven irreversible structural phase transformations in Eu3+ activated LaPO4, La0.5Y0.5PO4, and YPO4 nanocrystals can be utilized for thermal history measurements in the temperature range of 200°C-1000°C. The changes in Eu3+ local surroundings due to temperature increase modified the intensity and emission spectra, and the intensity ratio of Eu3+ 5D0 -> 7F2 to 5D0 -> 7F1 emissions served as a highly-sensitive indicator of the highest temperature experienced by the nanocrystals. The proposed ratiometric readout strategy enhanced the accuracy of thermal history analysis.

Summary: This study investigates the correlation between optical properties, local symmetry, and crystal structure in CaF2 and BaF2 fluoride crystals doped with ErF3. The differences in optical properties between CaF2 and BaF2 crystals at room temperature are observed and attributed to the differences in cationic radius and dopant-host ionic radius. The determined symmetries and bond lengths of Er3+- F- ions in both crystals are reported. This study provides valuable insight into the development of lanthanide-doped optical materials.

Summary: Lifetime-based luminescence thermometry enables accurate deep-tissue monitoring of temperature changes, but short lifetimes and poor brightness limit its performance. A solution to these limitations is the design and optimization of luminescent nanothermometers co-doped with transition metal and lanthanide ions, which exhibit strong near-infrared emission and long temperature-dependent photoluminescence lifetime. These nanothermometers, combined with a custom-made instrument, allow for obtaining 2D thermal maps for deep-tissue thermal mapping. This study provides foundations for the deployment of lifetime-based thermometry for accurate deep-tissue temperature monitoring.

Summary: We present a hydrothermal synthesis method for ultrasmall Yb3+/Tm3+ co-doped Sr2LaF7 (SLF) upconversion phosphors. By varying the concentrations of Yb3+ (x = 10, 15, 20, and 25 mol%) and Tm3+ (y = 0.75, 1, 2, and 3 mol%), the emissions in the near IR spectral range were analyzed. Structural analysis revealed that Yb3+ and Tm3+ occupy the La3+ sites in the SLF host. The addition of Yb3+/Tm3+ ions significantly affected the lattice constant, particle size, and PL emission properties of the synthesized SLF nanophosphor. The optimal dopant concentrations for upconversion luminescence were found to be 20 mol% Yb3+ and 1 mol% Tm3+ with EDTA as the chelating agent. Strong upconversion emission of Tm3+ ions around 800 nm was achieved under 980 nm light excitation. The study suggests potential applications of ultrasmall Yb3+/Tm3+ co-doped SLF phosphors in fluorescent labels for bioimaging and security.

Summary: Colloidal stabilization is crucial for the preparation of magnetic nanoparticles for biomedical applications. In this study, tannic acid was used as a coating for barium hexaferrite nanoplatelets (BSHF NPLs) to achieve stability in aqueous media. The coated BSHF NPLs were characterized and their magnetic properties were measured. The stable colloids were tested in biological media, and the antimicrobial properties were examined. To enhance antimicrobial activity, tannic acid was used as a platform for the in-situ production of silver on BSHF NPLs. The hybrid material exhibited magnetic properties and excellent antimicrobial activity against Escherichia coli and Staphylococcus aureus.
