Eu 3+ doped ZnAl layered double hydroxides as calibrationless, fluorescent sensors for carbonate

The photoluminescence properties (PL) of Eu 3+ 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 2+ /Al 3+ /Eu 3+ LDHs and can be imple...

Zusammenfassung:The photoluminescence properties (PL) of Eu 3+ 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 2+ /Al 3+ /Eu 3+ LDHs and can be implemented as a remote optical sensor to detect intrusion of anions such as Cl − or CO 3 2− .
