- Abstract
- An Extended X-ray Absorption Fine Structure (EXAFS) analysis of the local structure of bismuth in silicate-glass
based opticalfiber preforms exhibiting broadband near-infrared luminescence is presented. The valence state of
the bismuth ions in alumino-silicate and yttria-alumino-silicate glass hosts is revealed to be Bi 3+ and the local
geometry is suggested to be a trigonal oxygen pyramid with the electron lone pair positioned opposite to the
oxygen atom plane. Furthermore we found that the incorporation of Y2O3into alumino-silicate glass host does
not result in any change in the surrounding Bi structure (literal)
