Abstract

Boric oxide based quaternary glasses in the system 20 PbF2– 20 TeO2 – (60-x) B2O3 – x Eu2O3 [where x = 0 to 2.5 mol%] have been prepared by melt quenching technique. The paper reports on different physical and optical properties of Eu3+ doped lead fluoroborate glass. In order to understand the role of Eu2O3 in these glasses, the parameters like density, molar volume, refractive index were investigated. The values of molar volume (Vm) increased with increase in density (ρ) of the glass samples. The calculated values of theoretical crystalline volume (Vc) were smaller than the experimental molar volume (Vm) which proves the amorphous nature of the samples; it was again experimentally ascertained by X-Ray Diffractogram. FT-IR spectra of the present glass system indicate that B2O3 acts as network former and exists in mainly [BO3] structural groups.
