Colour-Turnable Gallium Nitride Leds

A team of scientists from Lehigh University, W Chester University, Osaka University (Japan) and the University of Amsterdam, recently developed a new technique to generate colour-turnable LEDs. "This work could make it possible to tune between bright white and more comfortable warmer colours in commercial LEDs," senior author Volkmar Dierolf said in a Lehigh University press release. "It could pave the way for monolithic integration for simple colour tuning of a light bulb. It would also be beneficial for micro-LED displays, since it allows for higher density of pixels."
