Tokyo, Japan – Scientists from Tokyo Metropolitan University have developed a new electrode material for deep-ultraviolet (DUV) light-emitting diode applications. They used a cutting-edge deposition ...

To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been ...

Researchers who build nanoscale electronics have developed microsensors so tiny, they can fit 30,000 on one side of a penny. They are equipped with an integrated circuit, solar cells and ...

British inventors began experimenting with electric lighting in the 1830s, working on so-called arc lamps, while other scientists around the world focused on developing a functioning incandescent lamp ...

Research team at Seoul National University (Prof. Tae-Woo Lee) developed highly efficient large-area perovskite light-emitting diodes (PeLEDs) with an external quantum efficiency (EQE) of 22.5% and ...

As people across the globe are switching to LED lights in an effort to save energy and money, they may be making another problem worse. Light pollution has been a growing problem for decades, and the ...
