Abstract:

Calculations of the electronic structure of phosphate glasses are performed in the MO LCAO x(alpha) approximation discrete variation method. On the basis of an analysis of theoretical and experimental electronic spectra of the system BeO-P2O5 regularities are found in the formation of the valence band of alkaline-earth phosphate glasses with different types of anion sublattice. Data on the electronic structure are used to refine the models of short-range order; in particular, the possibility of oxygen in the threefold coordination state is confirmed. With the features of the spectrum of electronic states taken into account, localization of charge carriers, the nature of the optical transitions, and hole-transport phenomena are discussed.
