Abstract Among the various techniques used in luminescence thermometry, kinetics is considered least sensitive to perturbations related optical properties of medium containing phosphor. For this reason, temperature sensing and imaging using lifetime‐based thermometers are high interest for a wide range specific applications. However, most such thermometers, an increase leads shortening lifetime, which can hinder specificity accuracy readout. In work, approach presented that utilizes thermally induced symmetry host material associated with structural phase transition LiYO 2 :Yb 3+ . Consequently, lifetime excited level F 5/2 Yb ion prolonged, achieving relative sensitivity 0.5%/K. The be controlled by adjusting dopant concentration. Additionally, thermal changes emission spectrum enable use ratiometric readout 5.3%/K at 280K :5%Yb

Luminescence thermometry (LT) has emerged as a valuable technique for noncontact temperature sensing, with applications in real-time monitoring, microelectronics thermal management, and health surveillance. In this work, we developed temperature-sensitive material, potassium chloride(KCl):Sb3+, investigated its luminescent properties. The results indicated that the material exhibited broad excitation spectra within 250–400 nm wavelength range maximum at 366 showed band emission 590 upon excitation. Interestingly, demonstrated excellent responsiveness over of 273 to 373 K, which not been observed so far. To explore potential application measurement, utilized fluorescence intensity ratio (FIR) dual bands Sb3+ Tb3+ emissions (ISb/ITb) sensitivity KCl:Sb3+/Tb3+. an exceptional relative ambient temperatures 5.59% K–1 313 K. This study could potentially serve centers luminescence fields.

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.
