Förster-Type Energy Transfer along a Specified Axis


  • This work was supported by the Schweizerischer Nationalfonds zur Förderung der wissenschaftlichen Forschung NF 200020-105140/1 and NRP47 4047-57481. Zeolite L was synthesized by Dr. A. Khatyr and Dr. S. Megelski. Time-resolved measurements were carried out by K. Lutkouskaya.

Quasi-1D transport of electronic excitation energy in dye-loaded zeolite L was observed when a spacer molecule was introduced between the donor and the acceptor dyes to separate them locally (see picture). In the system shown, the donor–spacer and spacer–acceptor phase boundaries are both diffuse. Alternatively, all the donors can be fixed at the same position and only the spacer–acceptor phase boundary is diffuse.
