Abstract

The red photoluminescence (PL) in oxygen deficient-type silica before and after high-dose γ irradiation was investigated as a function of temperature. A 1.8 eV PL band associated with an oxygen-deficient state was induced under a reduced partial oxygen pressure in the fabrication of silica glass by the Ar plasma method. The 1.8 eV PL band can be enhanced by up to 100 times in oxygen deficient-type silica glass by means of high-dose γ irradiation up to 10 MGy.
