Visible light transmission enhanced optical nano-ceramic heat-insulation glass and preparation method thereof

The invention relates to the technical field of functional glass, and in particular relates to visible light transmission enhanced optical nano-ceramic heat-insulation glass and a preparation method thereof. A nano-ceramic target material prepared by the method provided by the invention has the density greater than or equal to 98 percent and the purity greater than or equal to 99.99 percent. The nano-ceramic target material prepared by the method provided by the invention is applied to the heat-insulation functional glass, and a first TiO2 layer, a nano-ceramic film layer composed of XmZnCs0.3WO3 and a second TiO2 layer are formed on a glass substrate in sequence; under the common action of the nano-ceramic film layer, the first TiO2 layer and the second TiO2 layer, the prepared nano-ceramic heat-insulation glass has selective absorption and selective reflection properties on a solar spectrum; the high visible light transmission performance is ensured, and the nano-ceramic heat-insulation glass also can be us
