Light absorption is a cornerstone for several applications such as solar cells, photodetectors, and optical sensors, to name a few. Yet, the trade-off between the thickness of the absorber and its ...

Researchers at Hebei University in China and Hakkaido University in Japan have recently used a selective light absorber to construct a photothermal system that can generate temperatures up to 288°C ...

Researchers from the Shanghai Institute of Optics and Fine Mechanics (SIOM) of the Chinese Academy of Sciences have recently proposed a design concept for a tunable broadband perfect absorber based on ...

Researchers report their insights into how colors are generated on heated metal surfaces and apply those findings to create a nickel thin-film that perfectly absorbs red light. Researchers have ...

Researchers demonstrate how laser etching of metallic surfaces creates the ''perfect solar energy absorber.'' This not only enhances energy absorption from sunlight, but also reduces heat dissipation ...

Direct laser processing of material surfaces is a powerful technique for modifying the optical and electrical properties of those materials, often through the creation of nanostructures on the surface ...

(Nanowerk News) Researchers have discovered that the ancient technique of heating metal to create vibrant colors creates a nanostructured surface that acts as a perfect light absorber. Perfect light ...
