Summary: Mn4+-doped and Eu3+/Mn4+-codoped La2Mg1.33Ta0.67O6 phosphors were studied for their properties as optical thermometers. Mn4+-doped phosphors emitted intense red emissions, while Eu3+/Mn4+-codoped phosphors could be excited by different wavelengths and their luminescence behaviors could be manipulated by adjusting Eu3+ content. The thermometric performance of the phosphors was investigated by analyzing the fluorescence intensity rate and the temperature-dependent lifetime of Mn4+, and their maximum relative sensitivities were found to be 2.72% K-1 and 3.42% K-1, respectively, independent of the excitation wavelength.

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: Zinc titanate phosphors with Eu3+/Mn4+ as active ions were synthesized. XRD patterns confirmed a mixture of cubic Zn2TiO4 and hexagonal ZnTiO3 phases. The luminous intensity of ZTO: Eu3+ and ZTO: Mn4+ phosphors increased with doping concentration, reaching maximum values at 2 mol% Eu3+ and 0.3 mol% Mn4+, respectively. Photoluminescence spectra revealed characteristic peaks of Eu3+ at low Mn4+ content, and both Mn4+ and Eu3+ luminescence peaks at higher Mn4+ content. The relative sensitivity of the samples in variable temperature spectra improved with increasing Mn4+ concentration, reaching a maximum value of 3.2 %/K.

The method, called luminescence intensity ratio squared (LIR2), combines the advantages of dual-excitation single emission band ratiometric (SBR) and conventional luminescence intensity ratio (LIR) techniques. The LIR2 method demonstrates significantly enhanced thermometric performance compared to SBR and LIR techniques over a wide temperature range (300-850 K).

Summary: We demonstrate a thermal history forensic measurement method based on the emission intensity ratio of Eu3+-doped yttrium vanadate. By observing the increase in phosphor's crystallite size with annealing temperature, we found a significant and permanent increase in emission intensity and symmetry ratio, which serves as an indicator of the maximal temperature to which the phosphor was exposed. Additionally, the irreversible change in the symmetry ratio after exposure to high temperatures was found to be insensitive to the exposure time. Furthermore, thermal history readings can be performed at any temperature.

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.

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: YNbO4:xEu3+ powders with varying concentrations (0.1, 0.25, 0.5, 0.75, 1, 3, 5, 7.5, 10, 15, 20 mol %) were synthesized through a solid-state reaction and homogenization in a vibrational mill. The samples exhibited a monoclinic Fergusonite-beta-(Y) structure (C2/c space group) with crystallite sizes ranging from 45-65 nm. The samples showed strong orange/red luminescence with 5D0 excited state lifetimes of approximately 0.6 ms. Photoluminescence emission spectra indicated no concentration quenching within the examined concentration range. Judd-Ofelt intensity parameters showed a slight increase with increasing concentration, reaching a maximum of Omega(2) = 8.13 × 10(-20) cm(2), Omega(4) = 2.67 × 10(-20) cm(2), and an invariant value of Omega(6) at 0.35 × 10(-20) cm(2). The emission lifetimes of the 5D0 state remained nearly constant at around 0.6 ms with a slight decrease at the highest concentrations. The intrinsic quantum yield for all samples was approximately 0.5.

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: Dry olive leaf extract (DOLE) and its active component oleuropein (OLE) were used to synthesize colloidal silver nanoparticles (Ag NPs) with a size range of 20-25 nm. The cytotoxicity, genotoxicity, and antimicrobial activity of these Ag NPs were evaluated. The results showed that Ag/OLE exhibited the highest cytotoxicity, while Ag/DOLE and Ag/OLE did not induce genotoxic effects. Ag/OLE also demonstrated superior antimicrobial activity against different microorganisms compared to Ag/DOLE. However, the high concentrations of Ag/OLE could induce cytotoxicity in healthy human cells, suggesting potential risks.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
