Hybrid light-emitting polymer device fabricated on a metallic nanowire array

摘要

An electrode comprised of a copper nanowire array, fabricated by electrodeposition into a porous alumina membrane, is incorporated into a single-layer organic light-emitting device. The 48-nm-diameter copper nanowires form an array of electrical nanocontacts. Current-voltage and electroluminescence data for this device type are presented and compared with an equivalent planar copper electrode device. The nanowire array electrode device sustained a higher operating current density. The results show that such an array electrode can be used to inject charge in a polymer light-emitting diode, opening up the possibility of producing arrays of nanosized light sources using this approach.
