Abstract

Bismuth nanoclusters embedded in germanate glass matrices and surface layer of bismuth grains have been obtained by thermal treatment in hydrogen atmosphere of Bi0.33Ge0.67O1.84 and Bi0.57Si0.43O1.72 glasses. A simple two-layer model of reduced glasses, proposed by us on the basis of XRD and AFM studies, explains the evolution of surface layer and electrical properties of the materials during the reduction process.
