dc.description.abstractThe short-range order of vitreous V2O5 and of three (ZnO)x(V2O5)1-x glasses with x = 0.2, 0.4, and 0.5 is studied by X-ray and neutron diffraction experiments where the change of the contrast allows to resolve the V-O and Zn-O correlations. The V-O and the Zn-O first-neighbor peaks are approximated by several Gaussian functions. In case of vitreous V2O5 two obvious V-O distances exist which are related with VO4 and VO5 units. With ZnO additions the V-O coordination number decreases from 4.4 in vitreous V2O5 to 4.0 in the metavanadate glass where the strongest decrease of the fraction of VO5 units is found for glasses of x < 0.2. Dominantly, the VO5 groups are linked with the neighboring units by corners. The Zn-O coordination numbers of the modified glasses are about five with closest distances of ≅ 0.200 nm.
