Abstract

Novel optical absorbers are made using titanium metal and silicon dioxide thin films in specific layer thicknesses that create a low fractional reflectance and transmittance material. The absorbers have high absorption fraction measured from 200 - 1400 nm at normal incidence and specific reflectance band peaks. Layer thicknesses affect the wavelength at which light is reflected or absorbed and opens up tuneability for specific wavelengths within the visible spectrum depending on applications such as for solar cells and light modulation.
