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 ...
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 ...
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 ...
Shuji Nakamura already transformed the world once. His invention of blue light-emitting diodes (LEDs) changed everything about our daily lives. Computers, phones, big screens, traffic lights and ...
With the 2019 Nobel Prize for Physics due to be announced on Tuesday 8 October, Physics World journalists pick their favourite Nobel awards from the past. Here Margaret Harris argues the case for the ...
The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study from ...
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 ...
