摘要: Abstract The quaternary glass system xSiO 2 -(80-x) Bi O 3 15B 5TeO has been prepared by melt-quench technique. amorphous nature of samples ascertained X-ray diffraction patterns. variations in density, molar volume and crystalline with compositions have discussed. A non-linear change observed transition temperature optical band gap energy. Raman FTIR spectral studies suggest that network is mainly built up BO , 4 SiO TeO structural units, whereas BiO exists as both modifying [BiO 6 ] octahedral well forming pyramidal units. values energy estimated from fitting Mott Davis's model Hydrogenic excitonic (HEM) experimental data absorption spectra. HEM shows good agreement experimentally spectra, which indicates the exciton formation studied system. compositional related changes occurring present samples. Urbach also estimated. range metallization criterion suggests glasses may be considered new nonlinear materials.
