Real-time temperature feedback during hyperthermia enables precise lesion ablation with minimal damage to healthy tissue. However, the lack of on-demand theranostic agents eludes such applications. This study demonstrates in vivo operando monitoring tumor magnetothermal therapy using an optomagnetic heater-thermometer nanocluster agent. agent was synthesized via a microemulsion-based assembly lanthanide luminescent nanocrystals and superparamagnetic iron oxide nanoparticles. We show that within provide temperature-sensitive luminescence lifetime depth-sensitive intensity ratio second near-infrared biological window (NIR-II), enabling accurate 3D thermographic mapping tissues uncertainty as low 0.12 °C. Meanwhile, nanoparticles facilitate targeted accumulation lesions under oriented magnetic field act heating sources oscillating fields without interfering measurements nanothermometers.

Luminescence thermometry offers an attractive strategy for temperature sensing of a catalytic process, whereby the temperature-dependent luminescence phosphor material embedded in reactor is excited and recorded remotely. However, changes optical properties catalyst materials can distort recording, resulting inaccurate sensing. This particularly problematic hydrocarbon conversion catalysis due to buildup carbon deposits, which color cause fluorescence upon excitation. In this work, we developed operando reflectance-corrected time-gated thermometry, using highly dynamic industrially relevant Pt–Sn-based propane dehydrogenation (PDH) Eu3+-based as showcase. PDH deactivate via deposition carbon, subsequently removed by oxidative regeneration treatment. During these alternating reaction–regeneration processes, background change continuously. skews Eu3+ luminescence, leading temperature-readout artifacts. We solved problems rejecting detection following pulsed excitation correcting wavelength-dependent absorption catalyst. method accurate step forward development samples with properties.

Composition control is a powerful tool for obtaining high-performance lanthanide (Ln) luminescent materials with adjustable optical outputs. This strategy well-established hierarchically structured nanoparticles, but it rarely applied to molecular compounds due the limited number of metal centers within single unit.
