Black metals

摘要

Novel optical absorbers are made using titanium metal and silicon dioxide thin films in specific layer thicknessesthat create a low fractional reectance and transmittance material. The absorbers have high absorption fractionmeasured from 200 - 1400 nm at normal incidence and specific reectance band peaks. Layer thicknessesaffectthe wavelength at which light is reected or absorbed and opens up tuneability for specific wavelengths withinthe visible spectrum depending on applications such as for solar cells and light modulation.
