Thermal and spectroscopic studies have been carried out on a number of glasses with wide ranging compositions in the pseudoternary glass system Li 2 O+PbO+B 2 O 3 in order to understand the structural role of PbO in these glasses. Infrared, Raman, and 11 B MAS-NMR results indicate that PbO behaves a

The results of structural studies of the glasses from Li 2 O-Bi 2 O 3 -PbO system were presented. Infrared spectroscopy (FTIR) and photoelectron spectroscopy (XPS) were applied to determine main structural unites and chemical composition of near-surface region. Glasses from the studied system are bu
Effects of gamma-ray irradiation on some optical properties of xZnO AE 2xPbO AE (1-3x)B 2 O 3 glasses have been studied in the wavelength range 300-800 nm. Decrease in transmittance indicates the formation of color-center defects. Values for the energy-band gap, the width of the energy tail above th
