Shortwave infrared light (SWIR) sensors are desirable in a broad range of applications, particularly in the service robotics, automotive, and consumer electronics sectors. Colloidal quantum dots tuned ...

QLEDs — light-emitting diodes that rely on nanocrystals called quantum dots — are usually made with toxic heavy metals. A strategy has been developed to make QLEDs with a performance comparable to ...

Researchers have found a clever way to make quantum dots, tiny light-emitting crystals, produce streams of perfectly controlled photons without relying on expensive, complex electronics. By using a ...
