How to calibrate luminescent crossover thermometers: a note on “quasi”-Boltzmann systems
Benedikt Bendel, Markus Suta
Abstract
Boltzmann or not? Most luminescent thermometers rely on a configurational crossover between two excited states with high mutual non-radiative transition rates and relative sensitivity. It is shown that these materials follow a “quasi”-Boltzmann law as is demonstrated for the case of Sm 2+ .
