By taking advantage of the slight difference in the acidity of D 2 O and H 2 O, we report a novel D 2 O 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 D 2 O from H 2 O with high sensitivity and high accuracy.
