Layer of nanoparticles could improve LED performance and lifetime

Adding a layer of nanoparticles to LED designs could help them produce more light for the same energy, and also increase their lifetime. This is according to a team from Imperial College London and the Indian Institute of Technology (IIT) Guwahati who have found a new way to boost the amount of light LEDs produce. They report their innovation in the journal Light Science & Applications.

The authors believe that the principles used can work along with other existing schemes implemented for enhancing light extraction efficiency of LEDs. The same scheme could also apply to other optical devices where the transmission of light across interfaces is crucial, such as in solar cells.
