Thin cadmium sulphide film for radiative cooling application

Chemical solution deposition of the thin film CdS (1 mm) for radiative cooling is described and optical properties of the thin film were measured by an OL-750 Spectroradiometer. The radiative properties of the shield improved optical properties of cooling purposes; which indicates that it has very low IR band reflectance and is transparent across the full 8-13 μm.
