摘要

A translucent pane has, on one side of a substrate, a novel layer system comprising: (a) a 20-70 nm thick first layer of ZnO, SnO2, In2O3, B2O3, TiO2, ZrO2, Ta2O5, SiO2, Al2O3 or their mixts., AlN, Si3N4 or their mixts. or aluminium, titanium, zirconium and/or silicon oxynitrides; (b) a 1-40 (pref. 5) nm thick second layer of Zn and/or Ta suboxides; (c) a 5-30 nm thick third layer of metallic Ag and/or Cu; (d) a 0.5-5 (pref. 2) nm thick fourth layer of Ti, Cr, Nb or their mixt. or an alloy contg. at least 15 at.% of one of these metals, in metallic or suboxide form; and (e) a fifth layer of material as in the first layer. Pref. the substrate is a transparent inorganic or organic glass sheet or a transparent organic foil. Also claimed is a method of producing panes, with high transmission properties in the visible spectral region and with high reflection properties for thermal radiation, by cathodic sputter coating transparent substrates with the above layer system.
