Abstract

The influence of the environment on the fluorescence behavior of indicator molecules is investigated. A model is developed to describe the fluorescence decay of indicator molecules in a non-uniform medium. Its consequences for fluorescence decay time based chemical sensors are discussed and verified in two examples, namely a pH sensor using a pyrene compound in hydrogel and a ruthenium complex for oxygen sensing embedded in a polystyrene membrane.
