Abstract

Simulations of the Te K and L3-edge XANES in an Nb 2Te4O13 crystal are found to be in good agreement with experimental data for a large variety of tellurite crystals and glasses. The near-edge structure of the Te K and L3 edge is found to be determined by all the atom-position correlations within a cluster of about 5-8 Å in radius, rather than just the nearest neighbors. This suggests that the structure of tellurite glasses is closely related to those of crystals even in the range beyond nearest neighbors. Furthermore, it shows that XANES (and ELNES) technique can be used to probe intermediate-range structures around an absorbing atom.
