A new highly sensitive cryogenic luminescent MOF thermometer built with pyromellitic acid
A ratiometric thermometer based on a mixed Eu-Tb metal-organic framework is reported with a maximum relative thermal sensitivity of 16.1% K −1 at 11 K making this material one of the best-performing thermometers currently reported in the literature. The sensing mechanism of {[Tb 2− x Eu x (H 2 Btec)...
