Abstract

The feasibility of producing safety glass made from 3 mm sheet glass coated with chemically deposited CuS, ZnS-CuS, Sb₂S₃-CuS, and PbS-CuS thin films are presented. The coatings are produced on the sheet glass from dilute solutions containing metal complexes and a source of sulfide ions such as thiourea, thioacetamide, or thiosulfate. Films of thickness ranging from 0.05 micrometer to 0.3 micrometer are deposited at different temperatures, 10 degrees Celsius - 50 degrees Celsius, with durations of depositions of 1 h to 6 h. These coatings are laminated using commercially available poly(vinyl butyral) based laminating polymer sheets and clear sheet glass at temperatures of 120 degrees Celsius to 140 degrees Celsius under 10 - 12 kg cm^-2 pressure in an autoclave. The optical transmittance and reflectance spectra of the safety glasses show that a wide choice of solar control parameters are possible with these glazings: T_VIS, 2.5 - 45%; R_VIS, 10 - 25%; and shading coefficient (SC), 0.25 - 0.45.
