“…Recently, the reliability of luminescent nanothermometers has been improved using the combination of distinct thermometric parameters. [39][40][41] This strategy is based on the use of socalled multiparametric nanothermometers in which temperature impacts, simultaneously, different luminescence properties [42][43][44][45] or different emitting centers. [46][47][48][49] The use of different thermal readouts improves the reliability of temperature measurements by providing self-calibrated nanothermometers, increasing the precision of temperature measurement.…”

Luminescence thermometry has substantially progressed in the last decade, rapidly approaching the performance of concurrent technologies. Performance is usually assessed through the relative thermal sensitivity, Sr, and temperature uncertainty, δT. Until now, the state‐of‐the‐art values at ambient conditions do not exceed maximum Sr of 12.5% K−1 and minimum δT of 0.1 K. Although these numbers are satisfactory for most applications, they are insufficient for fields that require lower thermal uncertainties, such as biomedicine. This has motivated the development of materials with an improved thermal response, many of them responding to the temperature through distinct photophysical properties. This paper demonstrates how the performance of multiparametric luminescent thermometers can be further improved by simply applying new analysis routes. The synergy between multiparametric readouts and multiple linear regression makes possible a tenfold improvement in Sr and δT, reaching a world record of 50% K−1 and 0.05 K, respectively. This is achieved without requiring the development of new materials or upgrading the detection system as illustrated by using the green fluorescent protein and Ag2S nanoparticles. These results open a new era in biomedicine thanks to the development of new diagnosis tools based on the detection of super‐small temperature fluctuations in living specimens.

“…Temperature is a crucial parameter for most of industrial processes, like sintering, formation of metal alloys, catalytic reactions, formation of new materials under extreme conditions, and so forth. Hence, its rapid, accurate, and online monitoring is a challenging task for many specialists working in various fields of science, industrial researchers, and material engineers. − For these purposes, various luminescence thermometry techniques have been proposed, developed, and applied. − However, in general, because the luminescence of materials is significantly quenched at increasing temperature, these optical methods are usually limited to low- (cryogenic to biological; below ≈350 K) and mild-temperature (≈400–800 K) ranges. − …”

Lanthanide-based luminescent nanothermometers play a crucial role in optical temperature determination. However, because of the strong thermal quenching of the luminescence, as well as the deterioration of their sensitivity and resolution with temperature elevation, they can operate in a relatively low-temperature range, usually from cryogenic to ≈800 K. In this work, we show how to overcome these limitations and monitor very high-temperature values, with high sensitivity (≈2.1% K −1 ) and good thermal resolution (≈1.4 K) at around 1000 K. As an optical probe of temperature, we chose upconverting Yb 3+ −Tm 3+ codoped YVO 4 nanoparticles. For ratiometric sensing in the low-temperature range, we used the relative intensities of the Tm 3+ emissions associated with the 3 F 2,3 and 3 H 4 thermally coupled levels, that is, 3 F 2,3 → 3 H 6 / 3 H 4 → 3 H 6 (700/800 nm) band intensity ratio. In order to improve sensitivity and resolution in the high-temperature range, we used the 940/800 nm band intensity ratio of the nonthermally coupled levels of Yb 3+ ( 2 F 5/2 → 2 F 7/2 ) and Tm 3+ ( 3 H 4 → 3 H 6 ). These NIR bands are very intense, even at extreme temperature values, and their intensity ratio changes significantly, allowing accurate temperature sensing with high thermal and spatial resolutions. The results presented in this work may be particularly important for industrial applications, such as metallurgy, catalysis, high-temperature synthesis, materials processing and engineering, and so forth, which require rapid, contactless temperature monitoring at extreme conditions.

“…This idea gave rise to the concept of dual-mode sensing that is gaining in popularity. [23][24][25][26][27][28] Dual-mode sensing benefits from the possibility of cross-referencing sensor readings by using two methods, thereby improving reliability and accuracy of measurements. This concept received a fresh impetus recently when the feasibility of multimodal temperature sensing using three different techniques, i.e.…”
