How Do You Make The World’s Thinnest Light Bulb?

It’s one of the most talked about materials being researched today, and its advantages are still being discovered. It’s called graphene and it’s most recently been used to create “the world’s thinnest light bulb.”

Graphene is one atom thick and yet extremely strong and conductive. Scientists have been applying it to a number of different applications and systems in order to enhance conductivity, strength, and other properties, When used like the conventional filament in an incandescent light bulb, graphene is capable of producing heat and light.

“…the light that the graphene filament produces: It heats up to about the same temperature as an incandescent light bulb filament — 4,532 degrees Fahrenheit (2,500 degrees Celsius — and produces light that can be seen by the naked eye. However, the heat was concentrated in a small section of the graphene because it’s a poor conductor of heat at those temperatures, scientists found. What’s more, the color of the light can be changed by altering the distance between the filament and the substrate.”

While researchers are still working to understand how to best work with graphene and overcome its current manufacturing limitations, researchers have said that this material could be used to create windows and walls with built-in illumination, as well as transparent displays.
