A More Efficient LED Made from Fish Scales

Scientists from the Nagoya Institute of Technology (NITech) have developed an energy-efficient method to create a carbon nanostructure made from fish scales that results in a vastly more efficient LED.

The team has synthesized what are known as carbon nano-onions (CNOs) from fish scales, a form of carbon nanostructure that has excellent electrical and thermal conductivity. CNOs are nanostructures composed of concentric shells of fullerenes, resembling cages within cages.

This breakthrough in particular affects LEDs, and the team demonstrated their practical application there using blue-light-emitting thin films.
