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-.Chemical communications (Cambridge, England)Eu³⁺ doped ZnAl layered double hydroxides as calibrationless, fluorescent sensors for carbonate.PMC106449871010636562022/01314-82018/13837-0No. 834134 WATUSONo 101063656 MSCA-PF H2E2019/25665-12015/19210-088887.371434/2019-00834134Ferreira BJMustafa DSree SPBreynaert ETerraschke HTeixeira ACMorais AFSilva IGNGarcia FAfalseEu³⁺ doped ZnAl layered double hydroxides as calibrationless, fluorescent sensors for carbonate.The photoluminescence properties (PL) of Eu³⁺ hosted in the hydroxide layers of layered double hydroxides (LDHs) enables calibrationless quantification of anions in the interlayers.
