Abstract
Successive chemical bath depositions of ZnS (substrate film) with NiS (neutral density absorber film) and CuS (u.v. and i.r. absorber film) on glass substrates are described. These films exhibit a wide range of solar control characteristics. The use of such optical filters enable energy saving in space conditioning of buildings and offor visible transmittance of 7% - 28%, depending on the thickness of NiS and CuS films which is controlled by the durations of deposition
