Promising Candidates Revealed for Next-Generation LED-Based Data Communications

LEDLight-emitting diode (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 current state LED transmits data at far slower speeds than other wireless technologies such as light-fidelity (Li-Fi)

The researchers from Surrey and Cambridge, along with partners from the University of Electronic Science and Technology of China, examine how organic semiconductors, colloidal quantum dots (CQDs), and metal halide perovskites (perovskites), can be used in LED-based optical communications systems.
