ThesEuS (Thermometric Europium Simulator) is a freely downloadable MATLAB app, that implements a modified Mott-Seitz model used to predict the thermometric response of europium-based luminescent thermometers using specific molecular parameters. In the current version, three possible deactivation channels have been considered: two competitive metal-related terms describing the primary deactivation channels, i.e. back energy transfer and multiphonon quenching, and a third ligand-related term to describe non-radiative deactivation of the antenna triplet.
ThesEuS is based on a quite simple description of the temperature dependent phenomena with well-defined limits of applicability and predictive capabilities. As a general rule of thumb on the model performances: it will tend to provide the correct temperature range for the maximum sensitivity of the thermometer and hence, its range of applicability, with the numerical values of Sr being usually underestimated. In the worst-case scenario, hence, the real thermometer will show Sr values at least as predicted by the model.”
