Abstract:
Low-emissive (Low-ε) coating creates a surface that reflects heat (UV and Infrared radiations), while allowing visible light to pass through. It provides a solution to heat losses from the inside during the winters as well as blocking heat from the outside during the summers making it an energy efficient glass. The low-ε coatings are thin coatings of a few nanometers and can be coated via sputtering, spray pyrolysis or electrochemical deposition. Metallic coatings of Silver, Aluminum, Tin, Zinc etc give a low-ε value of around 0.05-0.10. The uniformity, stability and durability of these films is an important aspect of successfully deposition thin films on a glass substrate. These films will be characterized using SEM and UV-Vis-NIR spectroscopy
