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 ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much simpler to make. The scientists hope the breakthrough could lead to cheaper ...
