Abstract
The elastic moduli (Y, η, σ andH) and some thermodynamical parameters, such as Debye temperatureθD, diffusion constantDi and latent heat of melting ΔHm, of ZnF2-PbO-TeO2 glasses doped with some rare earth (Pr3+, Nd3+, Eu3+ and Tb3+) ions are determined as functions of temperature using piezo electric composite oscillator technique. All the parameters are found to decrease with increase in the atomic number Z of the rare earth ions and with increase in the temperature of measurement. The results are explained on the basis of the density of localized bonding defect states within the band gap of the material.
