摘要：
Glass samples of the system: 5M(x)O(y)-20B(2)O(3)-75TeO(2) : MA = WO3, Nb2O5, PbO, Nd2O3, Y2O3, Eu2O3 were prepared by melt quenching and characterized by X-ray diffraction, density, Differential Scanning Calorimetry, UVvisible and FTIR spectroscopy. XRD patterns confirmed the amorphous structure of all samples. Glass transition temperature was maximum in borotellurite glass containing Y2O3. Refractive index, atomic polarizability and basicity increased in the following order of ions: y(3+)< Eu3+ < Pb2+ < Nd3+ < Nb3+ < W6. FTIR studies showed that PbO is outstanding in enhancing the concentration of tetrahedral borons in the borotellurite network.
