Elastic properties of zinc-phosphate glasses doped with erbium trioxide

Abstract

New glasses of the system xEr2O3-(60-x)ZnO-40P2O5 (where x = 0.1 to 0.5 mol%) have been prepared by using a conventional meltquenching method. We have measured the densities of these glasses by using a displacement method, and corresponding molar volumes have also been calculated. We have measured both longitudinal and transverse ultrasonic sound velocities of these glasses using a pulse-echo superposition method. These ultrasonic velocities have been used to calculate the elastic moduli, Poisson ratio, and Debye temperatures. The variations of density, molar volume, ultrasonic sound velocities, elastic moduli, Poisson ratio, and Debye temperature have been discussed with respect to Er2O3 concentration.
