Abstract

The color of the electrofluorescence switching device was tuned to white by adding extra electroactive fluorophores with different emission colors. The reversible electrochemistry of fluorophores between neutral and anion radical was accompanied by fluorescence on and off, respectively, allowing fluorescence switching. Since the fluorophores have different emission color and also different redox potential, emission color could be further modified by quenching of the particular emission with precise voltage control. A reversible multicolor switching device was prepared by packing electroactive fluorophores blend of polymer electrolyte between ITO electrodes, and its emission color was examined with various fluorophore contents and potentials.
