Abstract
A layer of zinc oxide disposed on the surface of a substrate in thicknesses of between 500 and 10,000 Angstroms is characterized by a sharp absorption edge to substantially absorb selected wavelengths of radiation incident thereon while transmitting other selected wavelengths. The wavelength of the absorption edge is selectable as a function of temperature. A method of depositing the zinc oxide layer is also described.
