An infrared (IR) flashlight may not seem all that useful since humans can't perceive IR light, but they do have a purpose in ...

Researchers achieved that by combining mercury telluride colloidal quantum dots, which absorb infrared light, and a dual-layer OLED, which converts that absorbed energy into visible color. Stacked ...

Sunlight contains an electromagnetic spectrum (special waves such as the kind in x-rays that travel through emptiness or a vacuum) of light that stretches from very short gamma rays to very long radio ...

The invisible light spectrum, encompassing ultraviolet and infrared wavelengths, has long beguiled the human eye. A revolutionary lens technology is now making this unseen light accessible, heralding ...

A high-brightness ultrabroadband supercontinuum white laser has attracted more and more attention in physics, chemistry, biology, materials science, and other disciplines of science and technology.
