Structural analysis on the basis of effect of molybdenum on the Pr₂O₃ doped lead borate glasses series-II

This paper explains the role of molybdenum on the structural analysis of the investigated rare earth ion Pr³+ doped, lead borate (75 PbO — [25 – (x+y)]B₂O₃—yMoO₃—xPr₂O₃) glass matrix has been discussed using the relation between Tg and structural parameters like average cross-link density (${\bar{\text{n}}}_{\text{c}}$), average stretching force constant (F) and the number of bonds per unit volume (n_b). Densities, molar volume have been measured as a function of MoO3 content. Linear variation in density and in the molar volume has been observed and is credited to the role of MoO₃ in the investigated glasses. Based on the properties like good stability and bond strength, investigated glasses possibly suitable for the design of optoelectronic devices.
