Conjugated Polymer/Metal Nanowire Heterostructure Plasmonic Antennas

The spontaneous emission spectrum, polarization direction, and emission lifetime of monolithically coupled poly‐(3‐hexylthiophene), P3HT, light‐emitting nanostructures are modified by gold nanowire antennas. The P3HT nanostructure is integrated onto the end of the gold nanowire antenna, where locali...

Beschreibung
Zusammenfassung:	The spontaneous emission spectrum, polarization direction, and emission lifetime of monolithically coupled poly‐(3‐hexylthiophene), P3HT, light‐emitting nanostructures are modified by gold nanowire antennas. The P3HT nanostructure is integrated onto the end of the gold nanowire antenna, where localized, longitudinal surface plasmon mode fields are strongest. Comprehensive optical characterization and theoretical modeling are employed to demonstrate plasmonic nanoantenna‐mediated light emission from P3HT.
