Abstract

The invention discloses a one-way perspective low-emissivity glass, which comprises a glass substrate, a composite dielectric layer sequentially arranged along the thickness direction of the glass substrate, a first metal reflection layer, a preventing metal oxide layer, an intermediate composite dielectric layer, and a second metal reflection layer. Layer, light absorbing layer and composite dielectric protection layer, wherein, the thickness of the composite dielectric layer is 4-50nm, the thickness of the first metal reflection layer is 10-30nm, the thickness of the preventing metal oxide layer is 0.5-10nm, the middle composite dielectric layer The thickness of the second metal reflective layer is 5-20nm, the thickness of the light absorption layer is 0.5-20nm, and the thickness of the composite dielectric protection layer is 10-60nm. The one-way perspective low-emissivity glass has a firm, compact and simple structure, can increase the reflectivity of light on the surface of the observation object, reduce the reflectivity of light on the observation surface, reduce observation interference, and has both one-way perspective and low-radiation performance.
