The objective of this study is to investigate the principal role of Y2O3, Sc2O3 and HfO2 on the enhancement of 1.06 μm emission beam of Nd3+ ion in PbO–Sb2O3 glass system. The emission spectrum of Nd3+ doped glass exhibited emission bands at 900, 1060 and 1335 nm. When the glasses are co-doped with Y2O3, Sc2O3 and HfO2 and excited at 528 nm, a substantial hike in the intensity of 1060 nm emission...
