摘要：

We describe the spectroscopic properties associated with the occurrence of a 270 nm band giving rise to a blue luminescence at 432 nm and its dependence on the chemical composition in doped silica glasses. The luminescence lifetime is found at around 75 mu s. The associated defect is related to Ge doping. (C) 1998 Elsevier Science B.V. All rights reserved.
