Fluorescence properties of systems with multiple Förster transfer pairs

Abstract

A mathematical model has been developed to compute the spectroscopic properties of fluorescence systems with multiple Förster transfer pairs in a homogeneous 3-dimensional matrix. This model is based on Förster energy transfer theory and needs only a limited number of parameters which depend only on the properties of the individual dyes and their pair-wise interactions. Yet, the model allows the accurate prediction on the fluorescence properties of systems comprising mutual Förster transfer between three dyes. The model is compared to an experimental system composed of reverse micelles and water soluble dyes. Although the experimental system might include additional effects that may influence the fluorescence properties (e.g. adsorption to the micelle walls, aggregation of the dyes) the agreement between the mathematical model and the experimental system is reasonably good.
