Abstract
The dependence of the absorptivity and emissivity of lead sulfide films on thickness was investigated. Theoretical calculations were made using the bulk–lead sulfide model. Reflectance measurements in the visible and infrared regions of the spectrum were made to determine absorptivity and emissivity values. Both the theoretical and experimental results predict optimum a/e values for the lead sulfide thickness range 300–800 Å.Keywords
