Abstract :
Visible-region absorption and fluorescence are first observed for GeO2-doped silica optical fibres propagated by UV light in the 350¿370 nm region. An absorption band at 1.97 eV and fluorescence at 1.91 eV are observed in the UV-propagated fibre. The absorption and fluorescence are considered to be caused by creation of the oxygen-hole centre.
