Paper Abstract

An overview of the optical transmittance and reflectance characteristics of selected metal sulfide thin-film coatings obtained on glass substrates by chemical bath deposition is presented. The focus is on their application as solar control coatings, solar absorber coatings, decorative coatings, and as an imaging medium. Coatings of PbS-CuxS, Bi2S3- CuxS, SnS-CuxS, and ZnS-CuxS offer a range of solar control characteristics. Depending on the thickness of the individual films, solar absorptance of approximately equals 90% has been observed for SnS-CuxS and ZnS-CuxS thin films. Pleasant shades of colors observed in reflected daylight due to the thin film interference in these films together with the ease with which chemically deposited coatings can be obtained on cylindrical or planar substrates suggest the use of these films as decorative coatings. An application of these films as a photographic medium is possible based on the photo-accelerated chemical deposition of PbS and Bi2S3 thin films by which a specularly reflective image is obtained.
