Abstract

A new hybrid material, based on Er3+ exchanged zeolite L loaded with DFB molecules, is proposed as an efficient emitter in the third telecommunication window. The close proximity between the Er3+ ions and perfluorinated dyes, induced by the restricted geometry of the zeolite nanochannels, allows sensitized emission at 1.5 μm, with a lifetime >2 orders of magnitude longer than that for classic erbium organic complexes using nonfluorinated ligands. This approach, circumventing the requirement of the creation of real chemical bonds between the organic species and the metal ion, opens the way to using as an efficient antenna, the organic molecules for which the complexation to the metal ions cannot be realized. © 2010 American Chemical Society.
