Home > Press > Gold Nanoantennas boost the Emission Rate of Conjugated Polymers

Abstract:
Resonant plasmonic nanoantennas have been used to control the emission of light to various degrees, as the large local density of optical states in the near-field of the nanoantenna influences the emission properties. Theoretical studies have proposed to incorporate a semiconductor material into a metal nanoantenna, in analogy to the feed element in radio frequency antennas, in order to modify the semiconductor optical properties. Until now, however, the realization of such an integrated metal-semiconductor nanoantenna remained challenging.

Gold Nanoantennas boost the Emission Rate of Conjugated Polymers

Germany | Posted on June 8th, 2012

D. O'Carroll (Rutgers University) and co-workers have developed a novel fabrication process for metal-polymer-metal split-dipole nanoantenna heterostructures by sequential electrodeposition and thermal evaporation. The resonant scattering response of such antennas can be tuned to the polymer emission band by controlling the nanoantenna length. Using this approach, the radiative emission rate of poly(3-hexylthiophene) was enhanced by a factor of up to 29, in experiment, and 550 for the ideal case. Especially organic conjugated polymers such as polythiophenes, which exhibit high carrier mobilities but possess relatively poor luminescence properties, would benefit from incorporation into such plasmonic nanoantennas. This work demonstrates clearly that integrated metal-polymer-metal nanoantennas could enable a new generation of high-performance conjugated polymer optoelectronic devices.
