Abstract
The local structure of Ag2O-TeO2 glasses was studied by time-of-flight pulsed neutron diffraction (TOF-PND) and Raman spectroscopy. The results of Raman spectroscopy indicated that TeO4 trigonal bipyramidal units (tbp) were converted to TeO3 trigonal pyramidal units (tp) by addition of Ag2O to TeO2. Furthermore in PND, the structural parameters for each atomic pair were optimized in the Q-space, and the distances of the near neighbor Te-O correlations forming tbp units and tp units in the network were estimated with some accuracy.
