Abstract

Local structure in xLi₂O-(1-x)GeO₂ glasses (x = 0.17, 0.20, 0.24) were investigated by anomalous X-ray scattering and neutron diffraction. Coordination number and distance of Ge-O pair increased with increasing Li₂O content. Strong composition dependence of pair distribution between 2.5 and 3.5 Å were observed.
