Abstract

Glasses of the (1-x)[3Bi2O3·PbO]xR2O3 system where R=Er and Nd were prepared using the melt-quench technique. These glasses were characterized by density and magnetic susceptibility measurements and optical and infrared spectroscopy. Density data were used to calculate the Poisson’s ratio in terms of the Makishima-Mackenzie model. The temperature dependence of reciprocal magnetic susceptibility permitted to discuss the nature of complex interactions between rare earth ions localized in lead bismuthate glass matrix. The IR data permitted to identify some of the structural units that built up the lead bismuthate vitreous network. The optical spectroscopy data permitted to identify the electronic transition which occurs in these systems..
