Paper Abstract

The influence of aluminum ions on the UV optical absorption of germano-silicate sol-gel glass system is studied through investigating the variation of structure and photochemical transformation of germanium-related oxygen deficient centers (GODCs). The absorption spectra studies reveal that co- doping by aluminum and subsequent UV radiation effect the transformation of the GODCs from germanium lone pair center to neutral oxygen mono-vacancy in germano-silicate xerogel specimen. Possible mechanism of such an effect is discussed.
