Eu³⁺ doped ZnAl layered double hydroxides as calibrationless, fluorescent sensors for carbonate.

ABSTRACT: The photoluminescence properties (PL) of Eu³⁺ 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 Zn²⁺/Al³⁺/Eu³⁺ LDHs and can be implemented as a remote optical sensor to detect intrusion of anions such as Cl^- or CO₃^2-.
