Abstract
A transparent substrate provided with a functional stack of thin layers on at least one of its faces, the functional stack including, starting from the substrate, at least one metallic functional layer placed between two dielectric modules of thin layers, and wherein at least one of the dielectric modules of thin layers includes a layer of tungsten oxide having a physical thickness between 5 nm and 50 nm, and the tungsten oxide includes at least one doping element selected from the chemical elements of group 1 according to the IUPAC nomenclature or is pure substoichiometric, WOx.
Claims20
A glass substrate provided with a functional stack of thin layers on face thereof, said functional stack comprising, starting from the substrate, at least two metallic functional layers, each of the at least two metallic functional layers being located between two dielectric modules of thin layers and forming a succession comprising a first dielectric module, a first metallic functional layer, a second dielectric module, a second metallic functional layer and a last dielectric module, and wherein at least one of the first and second dielectric modules of thin layers comprises a tungsten oxide layer having a physical thickness of between 5 nm and 50 nm, and the tungsten oxide:
- comprising at least one doping element selected from the chemical elements of group 1 according to the IUPAC nomenclature, or
- being pure substoichiometric, WOx.
