“…There is no emergence of a new peak at high laser power density; in particular, the 2 H 9/2 → 4 I 13/2 intruding emission from Er 3+ was absent in the studied laser power density range. This phenomenon was considered as an important interference for the calculation of LIR. ,, In addition, it should be noted that the resolution is different between the two excitation conditions due to the different detector configuration and the different range of laser intensities.…”

“…The combination of optical heating and thermometry in Ln-doped materials was first studied by Wawrzynczyk et al, Debasu et al, and Pinol et al Subsequently, many works have described that the erbium-containing particles could be used as both nanothermometers and optical heaters, in different hosts such as fluoride, ,, oxide, molybdate, tungstate, phosphate, or vanadate. ,, Continuous-wave excitation is commonly used; however, non-steady-state upconversion based on pulsed excitation allows to avoid undesired nonradiative energy transfer. − In addition to the laser heating, there are other laser-induced effects in Er 3+ -doped composites.

Photoluminescent temperature sensors based on gadolinium orthovanadate (GdVO4) doped with 10% ytterbium and 2% erbium are developed and dispersed in different media (lubricant fluid, sol–gel glass, and PDMS) to evaluate the best conditions for temperature measurement. Two excitation modes are considered: (i) visible excitation by a downshifting (DS) process or (ii) NIR excitation by energy transfer upconversion (UC) between Yb and Er. The luminescence intensity ratio (LIR) of the thermally coupled Er3+ emission peaks varies linearly with temperature in the range of 25–300 °C, and this variation is reversible. The impact of the laser power density on thermometry via the UC process that has been verified with GdVO4: Yb3+/Er3+ powders and with its different dilutions (low and high concentration) shows that the LIR is highly dependent on the laser source intensity, the environmental temperature, and the dispersed medium. When GdVO4: Yb3+/Er3+ powders are dispersed at high concentration, high laser power density leads to significant laser-induced thermal heating. However, at low concentration, this laser thermal effect is no longer influenced by the laser intensity. In this paper, we propose a method to directly measure the laser-induced heating temperature and to correct the error caused by this effect on temperature measurement. According to these results, GdVO4: Yb3+/Er3+ upconversion nanoparticles can be applied for temperature sensing even if the laser-induced thermal effect occurs in the system.

Spotlight on Luminescence Thermometry: Basics, Challenges, and Cutting‐Edge Applications

et al. 2023

Luminescence (nano)thermometry is a remote sensing technique that relies on the temperature dependency of the luminescence features (e.g., bandshape, peak energy or intensity, and excited state lifetimes and risetimes) of a phosphor to measure temperature. This technique provides precise thermal readouts with superior spatial resolution in short acquisition times. Although luminescence thermometry is just starting to become a more mature subject, it exhibits enormous potential in several areas, e.g., optoelectronics, photonics, micro‐ and nanofluidics, and nanomedicine. This work reviews the latest trends in the field, including the establishment of a comprehensive theoretical background and standardized practices. The reliability, repeatability, and reproducibility of the technique are also discussed, along with the use of multiparametric analysis and artificial‐intelligence algorithms to enhance thermal readouts. In addition, examples are provided to underscore the challenges that luminescence thermometry faces, alongside the need for a continuous search and design of new materials, experimental techniques, and analysis procedures to improve the competitiveness, accessibility, and popularity of the technology
