A new class of ultrathin light absorbent material can absorb any wavelength of light from UV to microwaves, and then rapidly heat up to as high as 160 oC under sunlight in an open environment. The technology is believed to be suitable for a wide variety of uses such as desalination of seawater, color displays, photodetectors, and optical components for communication devices as it could simply harvest solar energy, boil water, and work as an infrared detector.
