“…[ 1a ] Figure 5 a depicts the temperature dependence of the relative sensitivity of spraydrying prepared Tb 0.914 Eu 0.086 -PDA in the range 10-325 K. The maximum sensitivity value of 5.96 ± 0.04% K −1 attained at 25 K is, to the best of our knowledge, the highest one reported in the cryogenic range (<100 K) for luminescent thermometers, in particular when compared with the: i) Eu/Tb-based MOF nanothermometers of Cui et al, [ 20,21 ] Cadiau et al, [ 22 ] Rao et al, [ 33 ] Zhou et al, [ 34 ] Wei et al, [ 35 ] Shen et al, [ 36 ] and Zhao et al, [ 37 ] which, although using distinct host matrices, adopt the same defi nition for the thermometric parameter; and ii) the nanothermometers of D'Vries et al, [ 38 ] which take the ratio between I 1 (or I 2 ) and the broad triplet band intensity. Additionally, Figure 5 a shows that, using distinct host matrices, Eu/Tb-based MOF nanothermometers cover the 10-340 K range with relative sensitivities in excess of 0.5% K −1 .…”

Accurate, noninvasive, and self-referenced temperature measurements at the submicrometer scale are of great interest, prompted by the ever-growing demands in the fi elds of nanotechnology and nanomedicine. The thermal dependence of the phosphor's luminescence provides high detection sensitivity and spatial resolution with short acquisition times in, e.g., biological fl uids, strong electromagnetic fi elds, and fast-moving objects. Here, it is shown that nanoparticles of [(Tb 0.914 Eu 0.086 ) 2 (PDA) 3 (H 2 O)]·2H 2 O (PDA = 1,4-phenylenediacetic acid), the fi rst lanthanide-organic framework prepared by the spray-drying method, are excellent nanothermometers operating in the solid state in the 10-325 K range (quantum yield of 0.25 at 370 nm, at room temperature). Intriguingly, this system is the most sensitive cryogenic nanothermometer reported so far, combining high sensitivity (up to 5.96 ± 0.04% K −1 at 25 K), reproducibility (in excess of 99%), and low-temperature uncertainty (0.02 K at 25 K).

“…Similar with common luminescent materials, the luminescence of MOFs can be influenced by many environmental factors,3, 4 including physical stimulus and chemical stimulus (ions,30, 31, 32, 33 solvents,34, 35, 36 vapors,37 pH,38, 39 gases,1 and so on40, 41, 42, 43, 44, 45). However, unlike other luminescent materials, the intrinsic porosity, large surface area, and strong adsorption affinity of MOFs can effectively enrich guest species.…”

Luminescence of porous coordination polymers (PCPs) or metal–organic frameworks (MOFs) is sensitive to the type and concentration of chemical species in the surrounding environment, because these materials combine the advantages of the highly regular porous structures and various luminescence mechanisms, as well as diversified host‐guest interactions. In the past few years, luminescent MOFs have attracted more and more attention for chemical sensing of gas‐phase analytes, including common gases and vapors of solids/liquids. While liquid‐phase and gas‐phase luminescence sensing by MOFs share similar mechanisms such as host‐guest electron and/or energy transfer, exiplex formation, and guest‐perturbing of excited‐state energy level and radiation pathways, via various types of host‐guest interactions, gas‐phase sensing has its unique advantages and challenges, such as easy utilization of encapsulated guest luminophores and difficulty for accurate measurement of the intensity change. This review summarizes recent progresses by using luminescent MOFs as reusable sensing materials for detection of gases and vapors of solids/liquids especially for O2, highlighting various strategies for improving the sensitivity, selectivity, stability, and accuracy, reducing the materials cost, and developing related devices.

“…Therefore, the luminescent nanothermometers can be grouped into six corresponding subclasses. The most widespread is the subclass of luminescent nanothermometers based on the analysis of relative fluorescence intensity between the different emission bands corresponding to the suitable transitions [1,9,13]. Among the most usable materials for luminescent nanothermometers such as quantum dots (QD) and dye-based luminescent nanothermometers, the rare-earth based materials have a special place mainly because of their excellent photostability, long luminescent lifetimes, sharp emission bands, and low toxicity which is highly important for biomedical application, for example, in photothermal and photodynamic therapies [14].…”

The main goal of this study was creating multifunctional nanoparticles based on rare-earth doped LaF 3 nanocrystals, which can be used as fluorescence thermal sensors operating over the 80-320 K temperature range including physiological temperature range (10-50 ∘ C). The Pr 3+ :LaF 3 ( Pr = 1%) microcrystalline powder and the Pr 3+ :LaF 3 ( Pr = 12%, 20%) nanoparticles were studied. It was proved that all the samples were capable of thermal sensing into the temperature range from 80 to 320 K. It was revealed that the mechanisms of temperature sensitivity for the microcrystalline powder and the nanoparticles are different. In the powder, the 3 P 1 and 3 P 0 states of Pr 3+ ion share their electronic populations according to the Boltzmann and thermalization of the 3 P 1 state takes place. In the nanoparticles, two temperature dependent mechanisms were suggested: energy migration within 3 P 0 state in the temperature range from 80 K to 200 K followed by quenching of 3 P 0 state by OH groups at higher temperatures. The values of the relative sensitivities for the Pr 3+ :LaF 3 ( Pr = 1%) microcrystalline powder and the Pr 3+ :LaF 3 ( Pr = 12%, 20%) nanoparticles into the physiological temperature range (at 45 ∘ C) were 1, 0.5, and 0.3% ∘ C −1 , respectively.
