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 ...

Perovskite light-emitting diodes have drawn great attention in the fields of displays and lighting, especially for applications requiring high efficiency and high brightness. While three-dimensional ...

Though we’re still galaxies away from having real lightsabers, the wonderful people in charge of Star Wars merchandising has given us the next best thing-LED flash light lightsabers. The Star Wars ...

Call it the fifth generation of light—the availability of electric lights that promote health and well-being by automatically mimicking the natural cycle of light. They switch between blue-rich ...

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 ...

When you flip a switch or power up your smartphone, the last thing on your mind is whether that light could be messing with your body's internal systems. Yet here's something lighting manufacturers ...

It’s hard to believe that the first blue LED didn’t arrive until 1993. They look simple, but looks are deceiving (Fig. 1). 1. Image showing a blue InGaN-based LED with gold wire contacts (0.4 × 0.4 mm ...
