Document Type and Number:
WIPO Patent Application WO/2023/143884
Kind Code:
A1
Abstract:
The invention relates to a transparent substrate (1000) provided, on one of its main surfaces, with a stack (1001) of thin layers, the stack (1001) of layers consisting of the following layers starting from the substrate (1000): - a first dielectric module (1002) of one or more thin layers; - an absorbent layer (1003) of tungsten oxide; - a second dielectric module (1004) of one or more thin layers; wherein the tungsten oxide comprises at least one dopant element selected from among the chemical elements of group 1 according to IUPAC nomenclature, the absorbent layer (1003) of tungsten oxide comprises cesium as the dopant element, and the molar ratio of cesium to tungsten is between 0.01 et 1, preferably between 0.01 and 0.4.
