Europium(iii)–β-diketonate complex-containing nanohybrid luminescent pH detector†
Abstract
In this work, by loading an Eu3+–β-diketonate complex into LAPONITE®, we report an organic–inorganic hybrid pH detection system Eu3+(TTA)n@Lap that is valid under acid conditions, which can serve as highly robust, reliable, rapid responsive and sensitive fluorescent pH detector. In addition, this hybrid pH detector can be easily recovered and reused by simply treating with Et3N vapor.
