UK researchers show how organic semiconductors, CQDs and perovskites can be used in LED-based optical communications systems A new paper from the University of Surrey and the University of Cambridge has detailed how two relatively unexplored semiconducting materials can satisfy the telecommunication industry's hunger for enormous amounts of data at ever-greater speeds. LED-based communications techniques allow computing devices, including mobile phones, to communicate with one another by using infrared light. However, LED techniques are underused because in its...
