In many cities today, streets are lit by white lights, screens show vivid colors, and buildings glow with precise patterns of illumination, all depending on a small but important invention from the ...

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 ...

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 ...

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 ...

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 ...
