Abstract

The white light of technology Light-emitting diodes based on organic materials (known as OLEDs) are emerging as an attractive technology for a variety of lighting and display applications. If the performances of white-light OLEDs are improved, for example, they could be used to produce large-area lighting sources. That will require efficiencies on a par with existing technologies such as fluorescent tubes, which produce around 70 lumens per watt. That benchmark — 90 lumens per watt in fact — has now been achieved with OLEDs that make use of a novel emitter layer structure with high internal quantum efficiency, and high-index glass substrates to boost outcoupling efficiency. Before practical applications are possible, matters of cost, manufacturing methods and longevity need to be addressed, but the goal would be a future light source with a potentially smaller carbon footprint than today's technologies.
