SubsidieMeestersStrong-coupling-enhanced nanoparticle array organic light emitting diode
The project aims to enhance OLED efficiency using plasmonic nanostructures to achieve over 50% quantum efficiency, making them competitive with inorganic LEDs while reducing environmental impact.
Projectdetails
Introduction
We propose a radical new solution to the problem of increasing the efficiency of organic light-emitting diodes (OLEDs) based on modifying the light-matter coupling by nanostructures. All previous attempts to increase the efficiency of OLEDs to be competitive with commercial inorganic LEDs have failed. If successful, our new vision for strongly coupled organic light-emitting diodes (SCOLEDs) will bypass the existing technological bottleneck.
Environmental Impact
OLEDs can be fabricated from earth-abundant non-toxic materials using energy-efficient processes, in stark contrast to the present market-leading inorganic LEDs. However, despite their much lower environmental impact, the widespread deployment of OLEDs has been blocked by their limited efficiency.
Objectives
To achieve the required step-change in efficiency, plasmonic nanoparticle arrays will be used to enhance the coupling between light and matter within OLEDs. Our objectives are to:
- Enhance OLED efficiency to a level competitive with inorganic LEDs.
- Adjust the periodicity, size, and shape of the nanoparticles to control the color, polarization, and directional distribution of the emitted light.
Methodology
Analytic theory, numerical simulations, and nanofabrication will be combined with optical and electronic characterization across an interdisciplinary team with expertise ranging from materials science and electronics to photonics and quantum physics. This includes world-leading proficiency in nanoparticle arrays and strong light-matter coupling.
Ambitious Target
Our ambitious target is the proof-of-principle demonstration of an OLED with more than 50% external quantum efficiency and tailorable control of the properties of the emitted light.
Future Prospects
SCOLEDs offer the prospect of a breakthrough technology that will dramatically reduce the environmental impact of LED technology in lighting and display applications. Additionally, they will widen the palette of OLED applications to new and emerging areas such as:
- Electronic vehicles
- Augmented reality
- Urban agriculture
