In this work, effect of Li2O and Na2O on bismuth borate glasses have been investigated. The glass samples were prepared in composition 44B2O3 : 50Bi2O3 : 5Li2O : 1A2O3 and 44B2O3 : 50Bi2O3 : 5Na2O3 : 1A2O3 (where A2O3= Sm2O3 and Dy2O3).Glasses were prepared using the melt-quenching technique at 1,100 oc under normal atmosphere. The result found that, the density and molar volume of lithium bismuth borate glasses are less than sodium bismuth borate glasses both in Sm2O3 and Dy2O3. In addition, the optical absorption spectra and luminescence of lithium bismuth borate glasses are higher than sodium bismuth borate glasses both in Sm2O3 and Dy2O3.

In this work, the physical and optical properties of soda-lime-borate glasses doped with V2O5 concentration of 0.0 to 2.5 in mol% have been investigated. The glass samples were prepared by the normal melt-quench technique. The results show that the density and refractive index decreased with additional 0.5 mol% content of V2O5. Then both results increased with increasing V2O5 content from 1.0-2.5 mol%. The optical absorption spectra of glass samples were measured by UV-visible spectrophotometer in the wavelength range 300-1100 nm and color coordinate in CIEL*a*b* system. The absorption peaks locate around 605 and 960 nm for all V2O5 concentration that are associated to V4+ ions and produce the brown color.
