Alkali-free or -deficient glass body has an antireflection layer containing porous silica and phosphorus. Independent claims are also included for the following: (1) method for producing a glass body with an antireflection layer comprising immersing the glass body in a volatile solution containing phosphoric acid (H3PO4) and silica (SiO2), removing the body from the solution and tempering the body at a temperature below the glass transition temperature of the glass; and (2) solution containing H3PO4, acids, SiO2 sol and solvents. Preferred Features: The glass body further contains at least 1, preferably at least 7 wt.% boron oxide. |
