The fluorescence and Raman emission spectra of optical fibers have been measured in samples that were either irradiated or presented a drawing-induced absorption. It is shown that the red band at 650 nm is centered at slightly different values and displays a different width in each case. Raman spectroscopy revealed the presence of molecular oxygen in fibers exhibiting the drawing-induced peak and a further emission at 695 nm was detected in one such fiber. These results emphasize the role of stoichimetry upon the characteristics of these fibers. It is suggested that excess 02 may form (02)2 complexes that present emission bands in the same regions as the fibers.
