It’s reported that Researchers from Rensselaer Polytechnic Institute have created a new method for manufacturing green-colored LEDs with greatly enhanced light output.
Led by led by Christian Wetzel, professor of physics and the Wellfleet Constellation Professor of Future Chips at Rensselaer, the research team etched a nanoscale pattern at the interface between the LED's sapphire base and the layer of GaN that gives the LED its green color.

It has received a good result. The new technique results in green LEDs with significant enhancements in light extraction, internal efficiency, and light output.

According to Wetzel, currently, every computer monitor and television produces its picture by using red, blue, and green. And we already have powerful, inexpensive red and blue LEDs. A similar green LED should lead to a new generation of high-performance, energy-efficient display and illumination devices. This new research finding is an important step in the right direction."
