Abstract
Materials have been made that exhibit high absorption in the visible, near ultraviolet, and near infrared spectral region while simultaneously exhibiting low absorptivity in the thermal infrared. Exemplary of such materials is silicon which is etched in a reactive sputtering process in the presence of a sputterable material. Other materials exhibiting useful properties are produced by this method.
