Seung Yoon Ryu and co-workers demonstrate a unique and abnormal approach for organic light-emitting diodes (OLEDs) to enhance he external quantum efficiency using antibiotic ampicillin. Electroluminescence and scattering by the ampicillin microstructure make highly efficient top-emission OLEDs possible. The application of the scalability of various materials for optoelectronic devices.
