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.
层状双氢氧化物（LDHs）氢氧化物层中所含铕的光致发光特性（PL）能够对层间阴离子进行无校准定量分析。这一概念在锌/铝/铕层状双氢氧化物的硝酸根到碳酸根离子交换过程中得到了验证，并且可以作为一种远程光学传感器来检测诸如氯离子或碳酸根离子等阴离子的侵入。
