Luminescence (nano)thermometry is an increasingly important field for remote temperature sensing with high spatial resolution. Most typically, ratiometric sensing of the luminescence emission intensities of two thermally coupled emissive states based on a Boltzmann equilibrium is used to detect the local temperature. Dependent on the temperature range and preferred spectral window, various choices for potential candidates appear possible. Despite extensive experimental research in the field, a universal theory covering the basics of luminescence thermometry is virtually nonexistent. In this manuscript, a general theoretical framework of single ion luminescent thermometers is presented that offers simple, user-friendly guidelines for both the choice of an appropriate emitter and respective embedding host material for optimum temperature sensing. The results show that the optimum performance (thermal response and sensitivity) around T 0 is realized for an energy gap ∆E 21 between thermally coupled levels between 2k B T 0 and 3.41k B T 0. Analysis of the temperature-dependent excited state kinetics shows that host lattices in which ∆E 21 can be bridged by one or two phonons are preferred over hosts in which higher order phonon processes are required. Such a framework is relevant for both a fundamental understanding of luminescent thermometers but also the targeted design of novel and superior luminescent (nano)thermometers.

“…However, by introducing additional relaxation pathways, e.g., through cross relaxation at higher Eu 3+ concentrations, the temperature regime for luminescence thermometry can be shifted toward lower temperatures. The present analysis shows that the validity of Boltzmann statistics needs to be considered in the application of luminescence thermometry based on both E [Eu 3+ − (this work), compared to Dy 3+ -doped samples [18,19,47,48] and Er 3+ -doped samples [17,[26][27][28]49]] and the dopant concentration (Fig. 5).…”

Non-Boltzmann Luminescence in NaYF4:Eu3+ : Implications for Luminescence Thermomet

Luminescence (nano)thermometry is an important technique for remote temperature sensing. The recent development of lanthanide-doped nanoparticles with temperature-dependent emission has expanded the field of applications, especially for ratiometric methods relying on the temperature variation of relative emission intensities from thermally coupled energy levels. Analysis and calibration of the temperature dependence is based on a Boltzmann equilibrium for the coupled levels. To investigate the validity of this assumption, we analyze and model thermal equilibration for Eu 3+ 5 D 1 and 5 D 0 emission in NaYF 4. The results show that for low Eu 3+ concentrations, temperature-dependent multiphonon relaxation can accurately explain both the intensity ratio and emission decay dynamics. The analysis also reveals that a Boltzmann equilibrium is not realized in the temperature regime investigated (300-900 K). By increasing the Eu 3+ concentration, cross relaxation between neighboring Eu 3+ ions enhances 5 D 1-5 D 0 relaxation rates and extends the temperature range in which emission intensity ratios can be used for temperature sensing (500-900+ K). The results obtained are important for recognizing, understanding, and controlling deviations from Boltzmann behavior in luminescence (nano)thermometry. By varying the dopant concentration, the range for accurate temperature sensing can be adjusted. These insights are crucial in the development and understanding of reliable temperature sensors.

“…In the photoluminescence spectra of DySuc ( Figure S18, SI section), all typical signals related to the Dy 3+ ions were observed. 29,30 The highest peak at 365 nm is regarding the transition from the ground state 6 H 15/2 to the excited state 4 I 13/2 . The emission spectrum (λ exc = 350 nm) shows an intense signal at 574 nm, due to the transition 4 F 9/2 → 6 H 13/2 .…”

Composites derived from coordination polymers have been gathering great attention due to their singular properties and applications, especially catalysis and adsorption. In this work, seven new composites based on activated carbon (AC) and lanthanide-succinates (LnSuc; Ln = Pr, Nd, Sm, Gd, Dy, Er and Tm, and Suc = succinate) 3D-coordination polymers were obtained using hydrothermal reactions. Coordination polymers in LnSuc@AC composites (Ln = Pr, Nd, Sm, Gd) crystallize in monoclinic system and C2/c space group. However, the LnSuc in composites with Dy, Er and Tm have different crystal structures, due to the influence of the carbon matrix in the reaction. The systems were also characterized by Fourier transform infrared (FTIR) and thermogravimetric (TGA) analysis, and the results are in agreement with the X-ray powder diffraction (XRPD) data. The scanning electron microscopy (SEM) images confirm the crystallization of the compounds inside the pores of the carbon material. Photophysical properties of the NdSuc@AC and DySuc@AC were also investigated.
