SUBSTRATE WITH STACKING WITH THERMAL PROPERTIES AND INTERCHANGE LAYER UNDER STOICHIOMETRIC

摘要

The invention relates to a substrate (10) coated on one side (11) of a stack of thin layers (14) with infrared reflection properties and / or solar radiation comprising a single metallic functional layer ( 140), in particular based on silver or metal alloy containing silver and two antireflection coatings (120, 160), said coatings each comprising at least one dielectric layer (122, 164), said functional layer (140 ) being disposed between the two antireflection coatings (120, 160), characterized in that at least one of said dielectric coatings (120, 160) comprises an intermediate layer comprising zinc oxide and tin oxide SnxZnyOz with a ratio of 0.1 ≤ x / y ≤ 2.4, with 0.75 (2x + y) ≤ z ≤ 0.95 (2x + y) and having a physical thickness of between 2 nm and 25 nm, or even between 2 nm and 12 nm.
