Check out the latest innovation in LED light technology developed by the researchers at the University of Illinois Urbana-Champaign. Combining different colors for lighting has been the basis for solid-state lighting, with red and green making yellow, blue and red making purple, and red, green, and blue making white. This process is key to meeting the 2035 DOE energy efficiency goals.
However, the challenge in reaching these goals lies in the “green gap”. The available green LEDs are not efficient enough, which is why increasing green LED efficiency is crucial. The latest research at the University of Illinois Urbana-Champaign has made significant strides in addressing this issue, reporting a green-emitting cubic III-nitride active layer with 32% internal quantum efficiency, a remarkable achievement in LED technology.
According to electrical and computer engineering professor Can Bayram, who led this work, “The ultimate goal is to triple the efficiency of today’s white light emitting diodes. And to do that, we need to fill the green gap in the spectrum, which is no easy task. You need innovation. And we show the innovation from the materials side by using cubic nitrides.” The results of this research were recently published in Applied Physics Letters as an issue cover article.
While most white LEDs currently use blue light emitting diodes with a phosphor coating that converts the blue light into yellow, green, and red, this process has its limitations. This is why the new research is so crucial, as it aims to improve efficiency and reduce costs associated with LED devices.
