Figure 1

(A) Dose-dependence of cathodoluminescence intensity of radiation-induced O2 molecules in stoichiometric silica samples, densified at 4 GPa and 5 GPa and T = 350C, 450C and 1000C; and in non-densified stoichiometric and oxygen-deficient samples (see Table 1). The respective densities (in g/cm3) measured after the irradiation are indicated. The samples did not contain interstitial O2 prior to irradiation. (B) Evolution with dose of the 1Δg → 3∑-g CL emission of O2 in non-densified SiO2. These spectra provide data-points for the blue (top) curve in panel (A).
