Popis: Modifications of a soda-lime silicate glass under thermal poling in corona discharge (CDP) in air and in dry nitrogen is studied with micro Raman technique to evaluate the possibility of glass structuration using poling in nitrogen. It is shown that CDP in dry nitrogen, contrary to CDP in atmospheric air, increases the concentration of silicon-oxygen tetrahedra bound into three-member rings in the subsurface region of the glass. The formation of the three-member rings is accompanied by the release of molecular oxygen.
