Fabrication, linear/nonlinear optical properties, Judd–Ofelt parameters and gamma-ray attenuation capacity of Er2O3 doped P2O5–ZnO–CdO glasses

Multicomponent glasses doped with erbium oxide 70P2O5–14ZnO-(15-x)CdO-xEr2O3 (where x = 1, 2, 3, 4, 5 and 6 mol%) named as [Er1 →Er6] have been prepared using the melt quenching method. The density was increased with increasing Er2O3 content and the molar volume increased linearly showing exactly li...
