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 ...
