发光镧系元素络合物（LLC）是用于测定多种分析物（如金属离子、阴离子、过氧化氢、ATP、pH或氧）的通用探针。天线生色团已被引入作为配体敏化镧系元素的发射。配体系统或镧系元素离子可以充当分析物可逆结合的受体。因此，发光发射的响应可以通过配体或金属为中心的过程发生，这两者都将被讨论。LLC，特别是Eu 3+和Tb 3+络合物，已经被掺入固态基质中，聚合物水凝胶或二氧化硅以获得光学传感器层。将概述这种敏感材料的选择，包括用于分析相关参数氧、pH值、过氧化氢、湿度和温度的传感器。
Luminescent lanthanide complexes (LLCs) are versatile probes for the determination of a variety of analytes such as metal ions, anions, hydrogen peroxide, ATP, pH, or oxygen. Antenna chromophores have been introduced as ligands for sensitizing lanthanide emission. The ligand system or the lanthanide ion can act as receptors for reversible binding of analytes. Thus, the response of luminescence emission can occur via ligand or metal-centered processes, which will both be discussed. LLCs, particularly Eu3+ and Tb3+ complexes, have been incorporated in solid state matrices, e.g., polymer hydrogels or silica to obtain optical sensor layers. A selection of such sensitive materials will be outlined, including sensors for the analytically relevant parameters oxygen, pH, hydrogen peroxide, humidity, and temperature.
