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 ...

The deep blue of your LED display is likely produced by indium gallium nitride (InGaN), a costly substance. In the field of LEDs, researchers are seeking alternatives in a type of perovskite known as ...

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 ...

Microscopic light-emitting diodes (LEDs) have applications ranging from augmented-reality displays to large-screen products, but their brightness typically decreases as their size is reduced. A ...

Research has achieved a breakthrough in eco-friendly display technology, creating highly efficient and stable blue quantum dot LEDs (QLEDs) that could power the next generation of televisions, ...

For the first time, researchers have created blue LEDs using layers of metal halide perovskite linked with asymmetrical bridges, solving a critical instability problem. From street and household ...
