The photoluminescence properties (PL) of Eu hosted in the hydroxide layers of layered double hydroxides (LDHs) enables calibrationless quantification of anions in the interlayers. The concept is demonstrated during the nitrate-to-carbonate ion exchange in Zn/Al/Eu LDHs and can be implemented as a remote optical sensor to detect intrusion of anions such as Cl or CO.
