Abstract
A transparent layered element with diffuse reflection properties includes two outer layers made of dielectric materials having substantially the same refractive index and a central layer intercalated between the two outer layers, formed either from a single layer which is a dielectric layer with a refractive index different from that of the outer layers or a metallic layer, or from a stack of layers which includes at least one dielectric layer with a refractive index different from that of the outer layers or a metallic layer. The upper outer layer is a sol-gel layer including a silica-based organic/inorganic hybrid matrix.
