Summary: The study demonstrates optical temperature sensing based on UCNPs with enhanced sensitivity through dielectric superlensing modulation, resulting in over a 70% increase in thermal sensitivity of the composite film compared to without the superlens. This enhancement is attributed to the modulation of the dielectric superlensing effect on the wave front of upconversion ultraviolet fluorescence.

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: Contactless thermometers based on fluorescence intensity ratio have advantages over traditional contact thermometers, but few materials are suitable for high temperature measurement. This study developed Y3GaO6:xPr3+ luminescent thermometers using Pr3+ as the emitter. The parameters for temperature measurement were determined by analyzing the peak intensity ratio at different temperatures. Y3GaO6: 0.01Pr3+ exhibited excellent temperature sensitivity, with a relative sensitivity of 4.09% K-1 in a wide temperature range. The varying luminescence colors of Y3GaO6:xPr3+ allowed for thermometric visualization.

Summary: The study focuses on Y3(Al,Ga)5O12:0.1%Pr phosphors with controlled Ga:Al composition to deliberately affect their luminescent properties. Results show that by tailoring the energy barrier for thermal quenching, the thermometric parameters of these phosphors can be fine tuned to cover a wider temperature range with higher relative sensitivity and lower temperature uncertainty. The relative temperature error between calculated and measured temperatures should also be considered when evaluating the performance of the thermometers.

Summary: To address the unsatisfactory pressure sensitivity of luminescent manometers, Eu2+-activated supersensitive microspheres operating in the visible range are developed. By synthesizing a series of Eu2+-doped Sr8Si4O12Cl8 materials and studying their structural and spectroscopic properties, it is found that the samples emit bright cyan luminescence at ambient conditions and undergo color changes under pressure. Most importantly, a huge red-shift of the emission band is observed as the pressure increases, leading to an ultrahigh-pressure sensitivity of 9.69 nm/GPa, which is the highest sensitivity ever reported. These designed microspheres with polychromatic emissions and high-pressure sensitivity are suitable for visual optical pressure sensing and provide important guidelines for the development of new optical manometers.

Summary: Nonlinear optical materials are crucial for various applications, including nanophotonics, optical information processing, and biomedical imaging. However, existing nanomaterials for these purposes are only efficient in one type of nonlinear optical activity. This study presents a new class of nanomaterials based on lanthanide-doped lithium niobate nanoparticles that simultaneously exhibit highly efficient second and third harmonic generation, as well as up-conversion photoluminescence. These nanoparticles retain their high conversion efficiency in both powder and aqueous colloidal solution forms, and offer technological potential in anti-counterfeiting and advanced optical information processing.

Summary: A multifunctional sensing platform based on photoluminescence (PL) and mechanoluminescence (ML) is created by combining heterojunctioned ZnS/CaZnOS:Mn2+ mechano-photonic materials and fiber spinning. Flexible optical devices capable of emitting light driven by mechanical force are developed by embedding ML-active particles in micrometer-sized cellulose fibers using a 3D-printing technique. The platform allows low-pressure sensing up to 100 bar and demonstrates a superior high-pressure sensitivity of 6.20 nm GPa(-1) using the developed optical manometer based on the PL of the materials. Four modes of temperature detection are achieved using this platform.

Summary: Luminescent manometry allows remote pressure readout with high resolution. In this study, a new approach utilizing the luminescence kinetics of Mn4+ ions in SrGdAlO4 is presented for remote pressure sensing. The unique feature of this method is the pressure-induced prolongation of the lifetime of Mn4+ ions, resulting from changes in the Mn4+-O2- bond covalency. By taking advantage of this effect, a luminescent manometer with a maximum relative sensitivity of 7.85%/GPa and sensitivities above 5%/GPa in the pressure range of 1-7.6 GPa was developed. Furthermore, the measurement was temperature invariant in the range of 260-365 K, with a manometric factor of 134.

Summary: The effects of intermolecular interactions and molecular conformations on the energy gap and optical properties of PTCDI-Ph were investigated under high pressure and various temperatures. PTCDI-Ph undergoes a phase transition from phase I to phase II below 498K, which is stable down to 93K at least. Phase II transforms into phase III above 3.0GPa. The compressed intermolecular distance between perylene cores narrows the band gap due to intensified π-π stacking. The PTCDI-Ph derivatives are highly stimuli-responsive organic materials with potential for tailoring their optoelectronic properties through physical and chemical modifications.

Summary: This study analyzes the impact of excitation and detection geometry, as well as sample thickness, on the spectroscopic properties and performance of luminescent thermometers. It finds that thick-layer samples exhibit significant changes in luminescence intensity ratios compared to thin-layer samples, resulting in different absolute and relative sensitivities for different sample thicknesses. These changes are attributed to a reabsorption effect, particularly pronounced in the transmission (back-illuminated) geometry of thick-layer samples. The results of this study have important implications for the accuracy of optical temperature monitoring using Er3+ ions.

Summary: This research focused on luminescence color tuning, white light generation, and ultra-sensitive temperature sensing using strontium vanadates doped with Eu3+ ions. By altering the vanadate to strontium ion ratios, a series of materials with different crystal structures were obtained. The materials exhibited changes in charge transfer band, Eu3+ ion emission characteristics, and luminescence intensity with varying vanadate content. The materials showed dual-mode luminescence with white and red light excitations. The luminescence color, chromaticity coordinates, color purity, quantum efficiency, and emission correlated color temperature of the materials were compared. The study also discussed the application of the optimized Sr3V2O8:2%Eu3+ material as a multimodal temperature sensor, which demonstrated high sensitivity. Additionally, the phosphors developed in this study were used for efficient energy conversion in white-light generation for LED devices.
