Abstract:
A vehicle window, includes at least one transparent glass pane and an IR-reflective coating on a surface of the glass pane, wherein the IR-reflective coating includes n metallic layers and (n+1) dielectric layer modules, wherein the layer modules are implemented as dielectric layers or layer sequences and wherein the layer modules and the metallic layers are arranged alternatingly such that each metallic layer is arranged between two layer modules, where n is a natural number greater than or equal to 1, wherein each metallic layer is implemented as a discontinuous layer of metal nanocrystals, which has regions that are occupied by metal nanocrystals and regions that are not occupied by nanocrystals. The uppermost layer module has a dielectric anti-reflection layer with a refractive index of at most 1.7.
