Model for Energy Transfer in Polymer/Dye Blends Based on Point−Surface Dipole Interaction
Source abstract
Abstract
We report a new model for the Förster energy transfer in blends of Nile Red dye in poly(9,9-dioctylfluorene) (PFO). We base our discussion on the possible arrangement of the dye molecules distributed in domains surrounded by polymer. These geometric considerations lead to a R - 3 functional dependence for the energy transfer, different from the R - 6 deduced by Förster for pointlike dipole−dipole interaction. The experimental value found for the Förster radius, namely 3.2 nm, is in good agreement with 3.6 nm obtained from the spectral overlap of donor emission and acceptor absorption.
