There’s a new type of LED in town. These light-emitting diodes (LEDs) are made from a material called perovskite, a calcium titanium oxide mineral that is more closely associated with cheap solar ...

Various properties of organic light-emitting diodes (OLEDs) have been optimized, including current to photon conversion efficiency. An external quantum efficiency exceeding 20%, with internal quantum ...

Organic Light Emitting Diodes (OLEDs) have gained significant attention since researchers at Eastman Kodak pioneered the development of OLED technology in the 1970s and demonstrated the first ...

Perovskite LEDs with the world's highest efficiency (EQE = 23.4%) -- Seoul National University and University of Pennsylvania Research team at Seoul National University (Prof. Tae-Woo Lee) and ...

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 ...

A diode is a semiconductor device that allows electrical current to flow in one direction while blocking it in the other.
