Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...

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 ...

Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light. This ...
