“…The patterned metal pads that produce a well-defined optical beam can at the same time be used as electrical contacts. Using such contacts, one can electrically pump a light-emitting device [28][29][30] , apply electric fields across electro-optic materials to modulate an optical signal 31 or even initiate electrochemical reactions. Here, we demonstrate how electric fields can be applied across the central slit of our beaming structures to tune the emission wavelength and intensity of QDs by means of the quantum-confined Stark effect 32,33 and luminescence quenching (Supplementary Methods).…”

nanometallic optical antennas are rapidly gaining popularity in applications that require exquisite control over light concentration and emission processes. The search is on for highperformance antennas that offer facile integration on chips. Here we demonstrate a new, easily fabricated optical antenna design that achieves an unprecedented level of control over fluorescent emission by combining concepts from plasmonics, radiative decay engineering and optical beaming. The antenna consists of a nanoscale plasmonic cavity filled with quantum dots coupled to a miniature grating structure that can be engineered to produce one or more highly collimated beams. Electromagnetic simulations and confocal microscopy were used to visualize the beaming process. The metals defining the plasmonic cavity can be utilized to electrically control the emission intensity and wavelength. These findings facilitate the realization of a new class of active optical antennas for use in new optical sources and a wide range of nanoscale optical spectroscopy applications.

“…However, if the metal surface is very close to a light emitter (e.g. fluorescent molecules or quantum dots), the SPs can be excited Figure 6 shows an electrically pumped SP source using organic light-emitting diode (OLED) structures (Koller 2008). The organic active layers are placed in between two gold layers (i.e., a metal-dielectric-metal structure, or MDM).…”

“…It was reported that 80% of the emitted light from OLED devices is confined in the substrate [6,7]. Various methods have been proposed to extract the emitted light, such as waveguide modes [8,9], micro lens arras [10] and utilization of surface plasmons [11,12]. The extraction of light from the OLED devices using surface plasmons is made by incorporated in the polymer emitting layer of the gold or silver nanoparticles.…”

Electroluminescence Enhancement of Polymer Light Emitting Diodes Through Surface Plasmons by Ag Nanoplates

et al. 2016

This paper reports a study on the surface plasmon effect of Ag nanoplates on electroluminescent property of polymer light emitting diodes. The diode is a single layer light emitting device made of poly [9,9-di-(2-ethylhexyl)-fluorenyl-2,7-diyl] (PEHF). 5 wt.% of Ag nanoplates were incorporated into the PEHF layer. The results showed that the electroluminescence intensity of the diodes is increased by 51.85%, compared with the device without the Ag nanoplates. The enhancement is due to the coupling process between the Ag surface plasmon with the emission light from the PEHF. The occurrence of the coupling process was proved firstly based on the fact that the exciton lifetime of the PEHF:Ag layer is shorter than that without Ag, as measured by time-resolved photoluminescence spectroscopy. Secondly, the PEHF photoluminescence peak at 425 nm is overlaping with the surface plasmon absorption peak of Ag nanoplates.
