Glass samples of the system: 5M{sub x}O{sub y}-20B{sub 2}O{sub 3}-75TeO{sub 2} : M{sub x}O{sub y} = WO{sub 3}, Nb{sub 2}O{sub 5}, PbO, Nd{sub 2}O{sub 3}, Y{sub 2}O{sub 3}, Eu{sub 2}O{sub 3} were prepared by melt quenching and characterized by X-ray diffraction, density, Differential Scanning Calorimetry, UV-visible and FTIR spectroscopy. XRD patterns confirmed the amorphous structure of all samples. Glass transition temperature was maximum in borotellurite glass containing Y{sub 2}O{sub 3}. Refractive index, atomic polarizability and basicity increased in the following order of ions: Y{sup 3+} < Eu{sup 3+} < Pb{sup 2+} < Nd{sup 3+} < Nb{sup 3+} < W{sup 6+}. FTIR studies showed that PbO is outstanding in enhancing the concentration of tetrahedral borons in the borotellurite network.
