Abstract

By taking advantage of the slight difference in the acidity of D₂O and H₂O, we report a novel D₂O optical sensor, namely Cy, with integrated great water-solubility, absorption/fluorescence dual-channel ratiometric response and even RGB visual sensing application. This work puts forward a facile method for distinguishing D₂O from H₂O with high sensitivity and high accuracy.
