LED lighting is bringing energy-efficient light to all corners of the globe. This year's Nobel Prize in physics was awarded to three Japanese scientists for the invention of blue light-emitting diodes ...

Three scientists, Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, have been awarded the Nobel Prize in Physics for their work on blue LEDs. Since the development of the first blue LEDs in the early ...

A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an ...

Light-emitting diodes (LEDs) are so ubiquitous that it's easy to forget just how much society relies on these underappreciated technological wonders. Yet, the history of the LED goes back further than ...

Deep blue: Scientists have developed hybrid copper iodide crystals that emit deep-blue light. (Courtesy: Kun Zhu/Jing Li Lab/Rutgers University) A team led by researchers at Rutgers University in the ...

With the invention of the first LED featuring a red color, it seemed only a matter of time before LEDs would appear with other colors. Indeed, soon green and other colors joined the LED revolution, ...

Perovskites, known for their potential use in solar cells, also hold promise for making low-cost, flexible light-emitting diode panels for lighting and displays. One hurdle that perovskite LEDs face ...
