| 摘要 |
The invention relates to a material comprising a transparent substrate coated with a stack of thin layers which, starting at the substrate, successively comprises three functional, silver-based metallic layers of increasing thickness and four dielectric coatings referred to as M1, M2, M3 and M4 moving outwards from the substrate, said layers and coatings being disposed alternately, characterized in that every dielectric coating has at least one high-index dielectric layer with a refractive index of at least 2.15 and an optical depth greater than 20 nm. |
