摘要: Abstract Novel quaternary tellurite glasses within the composition 75TeO2–10Nb2O5–10ZnO–5PbO (TNZP) doped with following Er3+ concentrations: 2500, 3750, 5000, 6250, 7500 and 8750 ppm have been prepared by using conventional melt quenching method. The thermal parameters, such as glass transition temperature (Tg), crystallization (Tc) stability (ΔТ) were determined. It is described that this system shows a stable formation, high low tendency crystallization. linear refractive index, n, optical energy gap, Eg, nonlinear n2, two photon absorption TPA, third order susceptibility, χ(3), of Moreover elastic properties like longitudinal (λ), shear (μ), Bulk (β) Young's (Y) moduli, Poisson's ratio, Debye temperature, microhardness evaluated measuring both velocities pulse-echo overlap technique at 5 MHz. present promising candidate for application.
