Scientists Create Carbon Nanotube-based Light Source that Behaves Like Cathodes Ray Tubes

 

Scientists from Tohoku University in Japan have created a new type of energy-efficient flat light source. The light source, which employs carbon nanotubes, has a very low power consumption of around 0.1 Watt for every hour's operation.

Many researchers have attempted to construct light sources with carbon nanotubes as field emitter but Japanese scientist made it.

Then what’s the principle of this new invents?

The researchers dispersed a mixture liquid containing highly crystalline single-walled carbon nanotubes in an organic solvent mixed with a soap-like chemical known as a surfactant. They "painted" the mixture onto the positive electrode or cathode. Then, they scratched the surface with sandpaper to form a light panel. According to the researchers, the light panel that they formed could produce a large, stable and homogenous emission current with low energy consumption.

There will be a potential way to provide a new approach to lighting.
