Going Above and Beyond: A Tenfold Gain in the Performance of Luminescence Thermometers Joining Multiparametric Sensing and Multiple Regression (Laser Photonics Rev. 15(11)/2021)

Abstract

Luminescence Nanothermometry Selecting green fluorescent protein and Ag2S nanocrystals as illustrative multiparametric thermographic phosphors, in article number 2100301, Luís D. Carlos and co-workers demonstrate that the synergy between multiparametric readouts and multiple linear regression makes possible a 10-fold improvement in the performance of luminescent thermometers reaching a world record in the relative thermal sensitivity (Sr = 50 %·K−1) and an impressive temperature uncertainty of 0.05 K.
