The thinnest light source is 0.335 nm thick and was created by researchers from Seoul National University, Korea Research Institute of Standards and Science, Konkuk University (all South Korea) and Columbia University (USA), as published on 15 June 2015.

The light source consists of a single layer of graphene, and emits light within the visible spectrum. This could prove a promising material for thin, flexible and transparent displays. The findings were published in Nature Nanotechnology on 15 June 2015.
