270 nm absorption and 432 nm luminescence bands in doped silica glasses

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 life-time is found at around 75 μs. The associated defect is related to Ge do...

Summary: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 life-time is found at around 75 μs. The associated defect is related to Ge doping.
