Abstract Luminescence (nano)thermometry is a remote sensing technique that relies on the temperature dependency of luminescence features (e.g., bandshape, peak energy or intensity, and excited state lifetimes risetimes) phosphor to measure temperature. This provides precise thermal readouts with superior spatial resolution in short acquisition times. Although thermometry just starting become more mature subject, it exhibits enormous potential several areas, e.g., optoelectronics, photonics, micro‐ nanofluidics, nanomedicine. work reviews latest trends field, including establishment comprehensive theoretical background standardized practices. The reliability, repeatability, reproducibility are also discussed, along use multiparametric analysis artificial‐intelligence algorithms enhance readouts. In addition, examples provided underscore challenges faces, alongside need for continuous search design new materials, experimental techniques, procedures improve competitiveness, accessibility, popularity technology

Thermal activation of upconversion luminescence in nanocrystals opens up new opportunities biotechnology and nanophotonics. However, it remains a daunting challenge to achieve smart control behavior the thermal field with remarkable enhancement ultrahigh sensitivity. Moreover, physical picture involved is also debatable. Here we report novel mechanistic design realize an ultrasensitive thermally activated erbium sublattice core-shell nanostructure. By enabling thermosensitive property into intermediate 4I11/2 level Er3+ through energy-migration-mediated surface interaction, upconverted was markedly enhanced together striking thermochromic feature under 1530 nm irradiation. Importantly, use non coupled red green emissions contributes sensitivity 5.27% K-1, 3 times higher than that obtained by using conventional emissions. We further demonstrate controllable interaction general approach for series lanthanide-based nanomaterials. Our findings pave way development luminescent materials toward emerging applications such as noncontact nanothermometry, information security, anticounterfeiting.

Abstract Fluorescence thermometry has been propelled to the forefront of scientific attention due its high spatial resolution and remote non‐invasive detection. However, recent generations thermometers still suffer from limited thermal sensitivity ( S r ) below 10% change per Kelvin. Herein, this work presents an ideal temperature‐responsive fluorescence material through Te 4+ ‐doped 0D Cs 2 ScCl 5 ·H O, in which isolated polyhedrons endow highly localized electronic structures, strong electron–phonon coupling facilitates formation self‐trapped excitons (STEs). With rising temperature, dramatic asymmetric expansion soft lattice induces increased defects, exciton–phonon coupling, low activation energy, evokes a rapid de‐trapping process STEs, enabling several orders magnitude changes lifetime over narrow temperature range. After regulating with different doping, record‐high (27.36% K −1 lifetime‐based detection is achieved at 325 K. The robust stability against multiple heating/cooling cycles long‐term measurements enables uncertainty 0.067 Further, developed are demonstrated for local monitoring operating on internal components. It believed that constitutes solid step towards building next generation ultrasensitive based low‐dimensional metal halides.

Abstract Nanothermometers enable the detection of temperature changes at microscopic scale, which is crucial for elucidating biological mechanisms and guiding treatment strategies. However, monitoring micron-scale structures in vivo using luminescent nanothermometers remains challenging, primarily due to severe scattering effect tissue that compromises imaging resolution. Herein, a lanthanide luminescence nanothermometer with working wavelength beyond 1500 nm developed achieve high-resolution vivo. The energy transfer between ions (Er 3+ Yb ) H 2 O molecules, called environment quenching assisted downshifting process, utilized establish temperature-sensitive emissions 1550 980 nm. Using an optimized thin active shell doped ions, nanothermometer’s thermal sensitivity emission intensity are enhanced by modulating process. Consequently, minimally invasive cerebrovascular system mice resolution nearly 200 μm achieved nanothermometer. This work points method micron-level vivo, potentially giving insights into research sensing, disease diagnosis, development.
