The inner workings of organic light-emitting diodes

Fig. Tianyi Ma on Unsplash.com How electrons and atomic nuclei make OLEDs glow Organic light-emitting diodes (OLEDs) can be used to generate light from electricity in a cost-effective and sustainable manner. Central to this is the use of efficient dye molecules. A team of theoretical chemists from the University of Vienna has now elucidated how these molecules function by means of computer simulations. Their results have now been published in the renowned journal "Angewandte Chemie" . Organic light-emitting diodes (OLEDs) light up the screens of smartphones, computers and TV sets. Compared with conventional, inorganic LEDs, they are more flexible, cheaper and more sustainable to produce.
