LEDs (Light Emitting Diodes) are everywhere. But how do these tiny components turn electricity into light? In this video, we explain the simple yet powerful science behind LEDs. You’ll learn how they ...

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 ...

Compared to incandescent lightbulbs, LEDs produce a lot more lumens per watt of input power — they’re more efficient at producing light. Of course, that means that incandescent light bulbs are more ...

Perovskites are promising candidates for use in next-generation light-emitting diode (LED) displays that are vivid and have high colour quality. LEDs made from particles with a perovskite nanocrystal ...

Stacking light-generating layers in ‘tandem’ light-emitting diodes (LEDs) can enhance performance, but achieving efficient and stable tandem LEDs made with perovskite materials has remained a ...
