Abstract

Tb and Eu ions were encapsulated for the first time in the inorganic layers of a synthetic saponite clay following a one-pot synthetic approach. The co-presence of the two metal ions led to tuneable light-emitting properties, promoted by an efficient Tb → Eu energy transfer and enhanced Stokes shift character. To our knowledge, the so-prepared luminescent material was tested for the first time as an optical sensor for the detection of chromate anions in water.

摘要

采用一锅合成法首次将铽（Tb）离子和铕（Eu）离子封装在合成皂石粘土的无机层中。两种金属离子的共存导致了可调节的发光特性，这是由高效的Tb→Eu能量转移和增强的斯托克斯位移特性所促进的。据我们所知，如此制备的发光材料首次作为光学传感器用于检测水中的铬酸根阴离子。
