Summary: Two experimental practices in luminescence intensity ratio thermometry, based on SD and WS, were analyzed for their performances in the case of sharp emission overlapping with a broad one. A new method named AD is proposed as an alternative, which retains the simplicity of WS while matching the sensitivities of the SD method. Although temperature resolution is not improved, the AD method allows fit to the Boltzmann equation and extraction of physically relevant parameters.

Summary: Nowadays, multi-mode luminescent thermometry has emerged as a strongly promising noncontact temperature-sensing technique. In this study, three-mode optical thermometry techniques were successfully designed using thermochromic Gd2GaSbO7 (GGS):Bi3+,Eu3+ phosphors. The GGS:Bi3+,Eu3+ phosphors showed remarkable variation in emission color with temperature, and the fluorescence intensity ratio of Bi3+ and Eu3+ provided outstanding relative sensitivity and temperature uncertainty. These discoveries suggest that GGS:Bi3+,Eu3+ phosphors have great potential in multi-mode temperature detection and high temperature warning areas.

Summary: Single doped CaWO4:Er3+ phosphors were synthesized and studied for optical thermal sensing within a wide temperature range. The ratiometric strategy using two luminescence intensity ratios improved thermometric characteristics and expanded the working temperature range. The thermometric performances of the samples were evaluated, and it was found that LIR1 had high sensitivity while LIR2 provided more accurate thermal sensing. The results indicate that CaWO4:Er3+ phosphors have potential in dual-mode thermal sensing.

Summary: Luminescence thermometry utilizes temperature-dependent light emission for remote sensing. Dy3+ ion is considered as a prospective ion for high-temperature probes, however, finding the best host is challenging due to the infinite number of potential hosts. The Judd-Ofelt thermometric model is experimentally validated on Dy3+ ion and shows excellent agreement with the experimentally obtained thermometric parameters and sensitivities, suggesting its potential application for quick assessment of luminescent sensor thermometry.

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: 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: 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.

Summary: In this study, 15 μm thick ZrO2:Nd3+ coatings were synthesized using the plasma electrolytic oxidation process with the addition of different concentrations of Nd2O3 powders. The coatings exhibited morphologies characterized by numerous pores and cracks, with uniform distribution of coating constituents. The XRD analysis revealed the dominant monoclinic phase and the stabilization of the tetragonal phase by Nd impurity. The Nd2O3 concentration was found to have a linear effect on the incorporation of Nd in the coatings. Photoluminescence spectra showed near-infrared emissions at typical energies for Nd3+ ion, with the highest emission intensity observed at 2.0 g/L Nd2O3. A novel equation for calculating the spectroscopic quality factor from the most intense emissions was presented, showing that the coating with the highest photoluminescent intensity had the lowest spectroscopic quality factor. The luminescence intensity decreased with temperature due to the phonon-assisted cross-relaxation mechanism, and luminescence thermometry showed a relative sensitivity of about 2% K-1 in the temperature range of 300-380 K.

Summary: In this study, the performance of single- and multiparametric luminescence thermometry based on the temperature-dependent spectral features of Ca6BaP4O17:Mn5+ near-infrared emission was investigated. Experimental results showed that as the temperature increased, the intensities of the T-3(2) and Stokes bands increased, while the peak of the E-1 emission band redshifted. The multiparametric luminescence thermometry showed comparable performance to the best single-parameter thermometry.

Summary: Luminescent coatings created by the electrochemical Plasma Electrolytic Oxidation (PEO) process have superior properties but are limited by the number of possible luminescent dopants. Adding various luminescent powders to the PEO coatings can result in superior coating performance. These polycrystalline coatings, with microhardness close to diamond, produce intense luminescence in the blue and red regions. The Al2O3:Eu2+/Sm2+/3+ + Y2O3:Eu3+ coatings show excellent temperature sensing performance and the proof-of-concept of a luminescent QR code with unprecedented environmental stability.
