Scientists to make brighter LEDs with nano-imprint lithography

Posted on Thursday, January 03 2008 @ 13:38:34 CET by


Scientists are using nano-imprint lithography to create brigther LEDs that could be used to replace regular bulbs:
The technology, used in gadgets such as mobile phones and computers, had previously not been powerful enough to be used for lighting.

But Glasgow University scientists said they had resolved the problem.

The project, being developed along with the Institute of Photonics at the University of Strathclyde, involves making microscopic holes in the surface of LEDs to increase the level of light they give off.

This is a process known as nano-imprint lithography.

Dr Faiz Rahman, who is leading the project, said: "As yet, LEDs have not been introduced as the standard lighting in homes because the process of making the holes is very time consuming and expensive.

"However, we believe we have found a way of imprinting the holes into billions of LEDs at a far greater speed, but at a much lower cost."
