Abstract

Electroluminescent polymeric nanofibers embedding dye-loaded zeolite L crystals are prepared. By exciting the polymer nanofiber, the energy is transferred to the fluorescent dyes inside the zeolite L channels through a two-step Förster resonant energy transfer process. This study opens new perspectives in the field of low-cost fabrication technology of flexible nanoscale OLEDs.
