First flashes of light observed from individual graphene nanoribbons

For the first time, researchers have experimentally observed light emission from individual graphene nanoribbons. They demonstrated that 7-atom-wide nanoribbons emit light at a high intensity that is comparable to bright light-emitting devices made from carbon nanotubes, and that the color can be tuned by adjusting the voltage. The findings may one day lead to the development of bright graphene-based light sources.
