Abstract

The present neutron-diffraction investigation aims to establish the effect of the second oxide component on the short-range atomic order in tellurite glassy systems: TeO2-MoO3, TeO2-V2O5, TeO2-Al2O3 and TeO2-P2O5. The experiments were carried out at λ = 0.1061 nm on the IRT-2000 reactor in Sofia and at λ = 0.0803 nm on the VVR-S pile in Řež. In both cases the maximum value of the scattering vector Q = 4π sinθ/λ attained was 100 nm−1. Experimental radial distribution functions (RDF), which are Fourier transforms of the neutron interference functions, were interpreted by comparison with the quasicrystalline model RDF’s, calculated by using the structural diffusion model.
