The blackest material ever created
Researchers from the King Abdulla University of Science and Technology in Saudi Arabia have created the blackest material ever made.
The researchers explained that engineering broadband light absorbers is crucial to many applications, including energy-harvesting devices and optical interconnects.
“The performances of an ideal absorber are that of a black body, a dark material that absorbs radiation at all angles and polarizations,” they said.
They described their breakthrough in a paper titled “Harnessing structural darkness in the visible and infrared wavelengths for a new source of light”.
In the paper, they described a “disordered nanostructured material” that shows an almost ideal black-body absorption of 98-99% between 400 and 1,400nm that is insensitive to the angle and polarization of the incident light.
