By embedding colloidal quantum dots in a high-mobility perovskite matrix, researchers at the University of Toronto in Canada and ShangaiTech University in China have succeeded in making a near-infrared (NIR) light-emitting diode (LED) with a record electroluminescence power conversion efficiency of nearly 5% for this type of device. The NIR LED could find use in applications such as night vision devices, biomedical imaging, optical communications and computing…..
