Molding resonant energy transfer by colloidal crystal: Dexter transfer and electroluminescence
PHOTONIC CRYSTAL MATERIALS AND DEVICES IX edition:SPIE location:Brussels date:12-15 April 2010
Building photonic crystals by combination of colloidal ordering and metal sputtering we were able to construct a system sensitive to an electrical field. In corresponding crystals we embedded the Dexter pair (Ir(ppy(3)) and BAlq) and investigated the influence of the band gap on the resonant energy transfer when the system is excited by light and by an electric field respectively. Our investigations extend applications of photonic crystals into the field of electroluminescence and LED technologies.
