Trivalent lanthanide ions have emerged as promising candidates for precise and remote temperature sensing. Among them, Pr3+-based luminescent thermometers remain underexplored, particularly those operating in the near-infrared (NIR) spectral region. This work presents synthesis thorough characterization of a novel coordination polymer, {[Pr2IIIPt3II(CN)12(4,4′-bpyO2)4(H2O)6]·4H2O}n (1), rare example Pr3+ thermometry. Coordination between ions, cyanido-bridged Pt2+ centers, 4,4′-bpyO2 ligands enables efficient energy transfer, producing luminescence visible regions. The polymer demonstrates distinct temperature-dependent over wide range (12–386 K), with relative thermal sensitivities ≅1%·K–1 minimum uncertainty 0.2 K.

Currently, developing luminescent materials for dual-mode optical thermometry has been becoming a rising topic, and concurrent temperature-sensitive parameters hold the key. Still, it is serious challenge, since distinct activators are generally needed energy transfer (ET) processes among inevitably occur, further leading to severe luminescence quenching. Herein, spatial separation strategy proposed designing dual-phase glass ceramics (GCs) containing ZnGa2O4:Cr3+ NaYF4:Yb3+,Er3+ nanocrystals (NCs) thermometry, in order integrate diversified into one. Structural, morphological, characterizations examined verify partition of Cr3+ ZnGa2O4 Er3+ NaYF4 lattice GC. Benefiting from such strategy, adverse ET between could be cut off GC, contributing downshifting (DS) upconversion (UC) luminescence. Furthermore, performed based on lifetime fluorescence intensity ratio (FIR) Er3+, with high relative sensitivities 0.95% K–1@450 K 1.24% K–1@303 K, respectively. It evidenced that GC holds great potential this work also offers prospective pathway expanding practical applications materials.

Fluorescent nanothermometers are positioned to revolutionize research into cell functions and provide strategies for early diagnostics. nanostructures hold particular promise fulfill this potential if nontoxic, stable varieties allowing precise temperature measurement with high thermal sensitivities can be fabricated. In work, we investigate the performance of micelle-encapsulated CuInS2/ZnS core/shell colloidal quantum dots (QDs) as fluorescent nanothermometers. We demonstrate four readout modes, which based on variations in photoluminescence intensity, energy, lifetime a specific ratio excitation efficiencies. further leverage multimodal construct fifth, multiparametric thermometer calibration multiple linear regression (MLR) model. show that MLR approach boosts sensitivity by up 7-fold while reducing error about factor 3. As result, our QDs offer highest among semiconducting emitting first biological window. The obtained results indicate excellent candidates intracellular vivo thermometry guidelines optimization their performance.
