Opis:: The antimony oxide as part of the heavy metal oxide glasses is attractive to researchers in recent years. The new antimony oxide glasses have been successfully synthesized using silica crucible in the ternary system for undoped and doped $(80-x)Sb_2O_3-20Li_2O-xMoO_3$ (x = 20, 30 mol.%) doped with 0.1 mol.% $CuO_2$. The optical characterization in the visible spectral region has been carried out on the doped glasses. The role of the Jahn-Teller effect in Cu doped glasses is determined and the electron transitions in these cations have been determined.

Opis:: We have analyzed the Co influence on the absorption spectra of $(80-x)Sb_2O_3-20Na_2O-xWO_3$ glasses in the Urbach rule region at room temperature. We present the comparison between Co and $WO_3$ manifestation in the spectral region 2.64-3.14 eV. The spectral characteristics of "crystalline" and "glassy" Urbach's rule are also calculated.

Opis:: New heavy metal oxide glasses involving $Sb_2O_3$ have been investigated. By using classical routes (melting-casting), glasses synthesized in silica crucibles were obtained in the combination of ternary systems $Sb_2O_3-M_2CO_3-MoO_3$ (M = Li and K). Characteristic temperatures such as glass transition $T_{g}$, and onset of the crystallization $T_{x}$, have been measured using differential scanning calorimeter. Ultrasonic velocities were measured by using pulse echo method to determine the elastics parameters, such as elastic modules (E, G, K, L). Other physical properties were measured, such as density and optical transmission window in far infrared spectra using KBr pellets. Influence of composition on these physico-chemical properties is discussed and correlated to the glass structure.
