New approach to increase the sensitivity of Tb–Eu-based luminescent thermometer†
Abstract
The formation of trimetallic terbium–europium–gadolinium complexes was proposed as an approach to increase the sensitivity of the corresponding terbium–europium complexes for temperature measurement due to the suppression of multiphotonic emission. This approach results in over a 2-fold increase of the sensitivity of Eu–Tb carboxylate, which reached 5.3% K−1 in the physiological range.
