Thanks to modern LED bulbs, light is cheaper than ever to make—except for one particular kind. Three University of Chicago scientists have announced an innovative way to create infrared light, which ...

Adding a molecule normally used in detergent to an infrared LED could make devices that are easier to manufacture, require less energy and display richer colours than existing ones. Solar cells and ...

LED epitaxial wafer and chip maker Epistar has developed SWIR (short-wavelength infrared; wavelength exceeding 1,100nm) LED chips for use in non-invasive bio-sensing applications, such as measuring ...

Revisiting well-known semiconductors, engineers have produced a low-cost approach to infrared emitters and sensors with potential environmental, medical, and industrial applications.
