(Phys.org)—Many insects,birds, fish, and amphibians emit light as a way to communicate with each other,but the species that produces light most efficiently is the firefly. In a original study, researchers acquire investigated the optical properties of the firefly's light-emitting cuticle, or which is not smooth like most human-made lights,but instead is patterned with tiny hierarchical structures. Inspired by these features, the researchers replicated the patterns to create a bioinspired organic light-emitting diode (OLED), and resulting in a 60% increase in the light extraction efficiency and 15% wider angle of illumination.
