Ratiometric mixed Eu-Tb metal-organic framework as a new cryogenic luminescent thermometer

We report a new mixed Eu-Tb metal-organic framework shown to be a highly effective dual-emitting luminescent thermometer within the cryogenic range and showing a relative thermal sensitivity of 3.26% K −1 at 35.5 K. The first example of a dual-emitting luminescent thermometer based on lanthanide iso...

Zusammenfassung:We report a new mixed Eu-Tb metal-organic framework shown to be a highly effective dual-emitting luminescent thermometer within the cryogenic range and showing a relative thermal sensitivity of 3.26% K −1 at 35.5 K. The first example of a dual-emitting luminescent thermometer based on lanthanide isophthalate exhibiting a maximum relative sensitivity of 3.26% K −1 , a temperature uncertainty of 0.07 K at 35.5 K, and a repeatability >99.9% between 12 and 230 K.
