Together with the collaborating groups of Prof. Dr. Luís Carlos from the University of Aveiro (Portugal) and of Prof. Dr. Daniel Jaque from the University of Madrid (Spain), we set up a new review on the latest developments, challenges and opportunities of luminescence (nano-)thermometry, which managed to enter the top-tier journal Advanced Materials! It includes a section about our assessments on the theoretical foundations of the thermodynamics and kinetics and the consequent design principles for such thermometers. The abstract is shown below.

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.
