摘要： The present invention provides a glass article including a photocatalyst film 1 containing silicon oxide particles 6 and titanium oxide particles 5, and a glass sheet 2. Assuming that the photocatalyst film 1 has a film thickness T, 80% or more of the titanium oxide particles are localized in a region between a surface of the glass sheet 2 and a position spaced from the surface by 0.6 T toward a surface of the photocatalyst film 1 in a thickness direction of the photocatalyst film 1. The glass article has an increased transmittance provided by enhancing the reflection-reducing function of the photocatalyst film 1 while maintaining the film strength and photocatalytic function of the photocatalyst film 1.

摘要： A low-reflection coating of the present invention is a porous film including: fine silica particles being solid and spherical and having an average particle diameter of 80 to 150 nm; and a binder containing silica as a main component, the fine silica particles being bound together by the binder. The binder further contains an aluminum compound. The low-reflection coating contains, as components, 55 to 70 mass % of the fine silica particles, 25 to 40 mass % of the silica of the binder, and 2 to 7 mass % of the aluminum compound in terms of Al2O3. The low-reflection coating has a thickness of 80 to 800 nm. The low-reflection coating yields a transmittance gain of 2.5% or more when provided on the substrate. The transmittance gain represents an increase in average transmittance of the substrate provided with the low-reflection coating relative to the substrate not provided with the low-reflection coating, the average transmittance being measured in the wavelength range of 380 to 850 nm.

摘要： A cover glass of the present invention for photoelectric conversion devices includes a glass sheet having surface asperities and a reflection-reducing film formed over the surface asperities of the glass sheet. The surface asperities of the glass sheet have an average spacing Sm of 0.3 mm or more and 2.5 mm or less and an arithmetic average roughness Ra of 0.3 μm to 5 μm. The reflection-reducing film includes fine silica particles having an average particle diameter of 50 to 200 nm and a binder for the fine silica particles, and the fine silica particles are uniformly arranged in a single layer on peak portions of the surface asperities in such a manner that a filling fraction F is 35 to 65%. A transmittance gain is 2.37% or more, the transmittance gain being obtained by subtracting an average transmittance of the glass sheet as measured when light having wavelengths ranging from 380 to 1100 nm are incident on a face of the glass sheet that has the surface asperities, from an average transmittance of the cover glass as measured when light having the wavelengths are incident on a reflection-reducing film side of the cover glass. Thus, a cover glass for photoelectric conversion devices that exhibits a high transmittance gain is provided.

摘要： A low-reflection coated glass sheet of the present invention includes a glass sheet and a low-reflection coating. The low-reflection coating is formed on at least a portion of one principal surface of the glass sheet, and contains a binder containing silica as a main component, fine silica particles bound by the binder, and fine titania particles bound by the binder. For the low-reflection coated glass sheet, a transmittance gain is 1.7% or more. The low-reflection coating contains 25 mass % to 43 mass % of the silica which is the main component of the binder, 40 mass % to 64 mass % of the fine silica particles, and 10 mass % to 20 mass % of the fine titania particles, based on the total mass of the low-reflection coating. As such, the low-reflection coated glass sheet of the present invention has high abrasion resistance and is capable of exhibiting photocatalytic properties and hydrophilicity when irradiated with light.
