摘要：

The photoluminescence in vitreous-SiO2 in the 4.0 to 4.5 eV region has been investigated by exciting with UV and vacuum-UV photons. Two emission bands, alpha(E) and alpha(I), centered at 4.26 and 4.42 eV respectively, are detected. They have distinct features: alpha(E) has an excitation profile extending from 7.0 to 8.2 eV and decays with a lifetime of 5.5 ns; alpha(I), has an excitation maximum at 6.8 eV and a decay time of 4.1 ns. The centers responsible for these optical activities are discussed, also on the basis of their behaviour under gamma-irradiation. (C) 1997 Elsevier Science B.V.
