Sensing of H2O in D2O: is there an easy way?

We report Tb–Eu based luminescence sensor materials toward H2O detection in D2O with the highest sensitivity of 24%/%(H2O), exceeding the previously reported ones by an order of magnitude. The theoretical description of such sensors based on the terbium–europium systems was performed and proved that...

Summary:We report Tb–Eu based luminescence sensor materials toward H2O detection in D2O with the highest sensitivity of 24%/%(H2O), exceeding the previously reported ones by an order of magnitude. The theoretical description of such sensors based on the terbium–europium systems was performed and proved that the sensitivity is proportional to the number of inner-sphere water molecules.
