Scientists have created the world's smallest light bulb from a one atom-thick layer of graphene, the miracle material that promises to transform everything from smartphones and computers to cars, buildings and satellites.

The ultrathin graphene was turned into a superheated filament, just like the thin wire of an incandescent light bulb, which glowed at a temperature of about 2500C, Science Daily reported.

"We've created what is essentially the world's thinnest light bulb.

This new type of 'broadband' light emitter can be integrated into chips and will pave the way towards the realization of atomically thin, flexible and transparent displays, and graphene-based on-chip optical communications," Professor Hone said.
