Abstract
The microstructure of thermally treated neodymium containing silica ge ls is investigated by transmission electron microscopy and electron di ffraction. Microheterogeneities with amorphous nature are found. Infor mation for the short range order is obtained by the Radial Distributio n Functions: SiO4 tetrahedra and NdO6 groups are formed and transition from four-fold to six-fold ring structure is observed with increasing of the heat treatment temperature.
