Irradiation Effects in Glasses: Suppression by Synthesis under High-Pressure Hydrogen.

ABSTRACT

Glasses synthesized under high pressure of hydrogen showed resistance to certain effects of irradiation. Paramagnetic and light-absorption effects associated with irradiated glasses were diminished by a factor as large as 20 in some glasses. Irradiation increases the concentration of hydroxyl ions, as evidenced by increased absorption in the 2.7-micron (3700 cm(-1)) infrared region for hydrogen-silica glasses.
