Black Metals: Optical Absorbers
We demonstrate a concept and fabrication of lithography-free layered metal-SiO2 thin-film structures which have reduced reflectivity (black appearance), to as low as 0.9%, with 4.9% broadband reflectance (8.9% for soda lime) in the 500−1400 nm range. The multi-layered (four layers) thin-fi...
