PLAS-OLED

The development of white light-emitting diodes (LEDs) and their use as a replacement for conventional lighting put these inorganic LEDs virtually everywhere. Famous for their luminescence and low power consumption, they are also increasingly in the spotlight for their use of rare earth and toxic heavy metals. Organic LEDs (OLEDs), whose luminescent layer is made of carbon-based (organic) molecular semiconductors rather than crystalline inorganic semiconductors, are emerging as a promising alternative, but they have about half the lifetime of inorganic LEDs and less luminance. The EU-funded PLAS-OLED project plans to use high-tech disruptive methods to convert monochromatic OLEDs into white OLEDs that compete with the best of their inorganic counterparts.
